Pet scale and pet weight are the same thing

Players searching pet scale grow a garden or grow a garden pet calculator usually want the same thing as this pet weight calculator: recover hatch weight from current kg + age, project the age curve, and read Huge / Titanic / Godly (and community Colossal) class. “Pet scale” is chat slang for how kg scales with age — not a separate tool. Verified September 20, 2026.

Search phrase	What to do in this tool
pet scale / GAG pet scale	Enter current kg + age → reverse hatch weight → see age-100 kg (~10× hatch)
pet calculator / GAG pet calculator	Same calculator — weight/class first; then open pet XP and cooldown for grind/ability
calculadora grow a garden pets	Same English tool and formulas (W ≈ (Wh ÷ 11) × (A + 10)); no separate Spanish calc required
Huge / Titanic / Godly	Class is set by hatch weight (Age 1), not by aging a light hatch to 100

Short answer: pet weight scales linearly with age. Formula W ≈ (Wh ÷ 11) × (A + 10). At age 100, W ≈ 10 × Wh. Use the tool above, then pet XP to age and pet cooldown for ability timing. Trade demand: pet value list + trade calculator.

What this Grow a Garden pet calculator does

A Grow a Garden pet weight calculator (also searched as GAG pet calculator, pet kg tool, or pet XP calculator) converts the stats on your pet card into planning math. It answers four questions players ask constantly: how heavy will this pet be at a target age, how much XP is left to get there, how long will this egg take with my hatch pets, and how trigger chance moves as weight rises.

Weight is not cosmetic for most pets. It scales ability strength, changes how cooldowns feel in practice, and sets the trade language for size classes. A light Raccoon and a heavy Raccoon are different assets even when the species name matches.

No login is required. Pick a calculation mode, enter the fields shown, and read the result. For egg-focused runs, pair with the egg hatch calculator. For ability cooldown curves after you know kg, use the pet cooldown calculator.

How to use the calculator

• Choose Pet Calculation Type: Pet XP Needed, Egg Hatch Speed, Pet Weight Progression, or Pet Ability Trigger Chance.
• XP mode: enter current age and target age (plus rarity-related XP fields the UI asks for).
• Hatch mode: base egg hours plus helper hatch-speed bonuses you will actually equip.
• Weight mode: hatch weight (Wh) and/or current weight + age to project future kg.
• Trigger mode: base chance and weight-related inputs shown in the panel.
• Read the result: treat it as planning math, then confirm the live tooltip. Screenshot the card for trades. Mismatch? Report it here.

Is this the Grow a Garden pet calculator?

Yes. Searchers looking for a Grow a Garden pet calculator, GAG pet calculator, or pet kg calculator land here because this tool is the pet hub: weight by age, hatch/base weight reverse, ability trigger chance, XP levels, and egg hatch hours. Updated September 22, 2026.

• Pet Weight Progression — kg from hatch weight + age (including Age 500)
• Pet Ability Trigger Chance — how often an ability can fire as kg/age scale
• Pet XP Needed — levels left to your target age
• Egg Hatch Speed — hours with helper pets

Need a full ability cooldown timer (seconds between procs)? That is the pet cooldown / ability calculator, not the weight progression mode. Need only XP grind math in depth? Open the pet XP calculator.

Age 500 pet weight (kg and age)

Most players who search kg and age 500 want one number: what the pet card will show at the current community age cap. Use the same formula as Age 100 — only the age changes.

Target age	Multiplier on hatch weight (Wh)	Quick example (Wh = 2 kg)
Age 1 (hatch)	≈ 1×	≈ 2 kg
Age 100	≈ 10×	≈ 20 kg
Age 500	≈ 46.36× (510 ÷ 11)	≈ 92.7 kg

Forward formula: W ≈ (Wh ÷ 11) × (A + 10). At Age 500: W ≈ (Wh ÷ 11) × 510. In the tool above, choose Pet Weight Progression, enter hatch weight, set Max Age to 500 (or your live in-game cap), and read max kg. Confirm the cap on your pet card after Saturday patches — older guides still say Age 100 or 125.

Age 100 vs Age 500 — which should you project?

• Age 100 — classic trade shorthand (~10× hatch); still useful in chat
• Age 500 — current long-grind ceiling most “age 500 calculator” searches mean
• Always match the Max Age field to the cap shown in your game, not an old wiki page

After you know Age 500 kg, check whether the species is worth the XP on the pet value list, then time the grind with pet XP.

Base weight vs current kg

Base weight (also called hatch weight or Age-1 kg) is the growth seed. Current kg is what the pet card shows after aging. Traders care about base/hatch weight for Huge / Titanic / Godly size labels — not the inflated Age 500 number alone.

• Know current kg + age → reverse: Wh ≈ (11 × W) ÷ (A + 10)
• Know hatch/base weight → forward to Age 100 or Age 500 with the formula above
• Ostrich can raise hatch age; it does not secretly create a Titanic base weight

Pet ability calculator vs this weight tool

GSC shows many pet ability calculator and cooldown calculator searches hitting this URL. Use the right mode:

What you searched	Use this	Why
Pet weight / kg and age / Age 500	Weight Progression (this page)	Projects kg from hatch + age
Pet size / Huge Titanic Godly	Weight Progression + size sections below	Class = hatch/base kg, not max age
Ability trigger chance	Ability Trigger Chance mode (this page)	Scales with kg and level
Ability cooldown timer	Pet cooldown calculator	Seconds between ability procs
Pet age / XP to level	XP mode here or pet XP calculator	Grind time to Age 100 / 500

The pet weight formula

Definition

• Hatch weight (Wh): kg when the pet first exists (the growth seed).
• Age (A): current age / level progress.
• Current weight (W): kg on the pet card now.
• Age multiplies hatch weight; it does not replace a weak hatch.

Formula

Use the same community model as the Direct Answer card. At age 1, W ≈ Wh. At age 100, W ≈ 10 × Wh.

Term	Meaning	Why it matters
Hatch weight (Wh)	kg when the pet first exists	Sets lifelong growth slope
Age (A)	Pet age / level progress	Feeds the weight formula
Current weight (W)	kg on the pet card now	Trade talk + ability scaling
Age-100 weight	≈ 10 × Wh	Long-term ceiling players quote

Worked examples

Forward: a pet hatched at 1.5 kg reaches about (1.5 ÷ 11) × (50 + 10) ≈ 8.18 kg at age 50, and about 15 kg at age 100.

Reverse: a pet showing 6 kg at age 40 had roughly (11 × 6) ÷ (40 + 10) ≈ 1.32 kg hatch weight. Plug either direction into Pet Weight Progression mode above.

Pet size labels traders use (Huge to Godly)

Direct answer: class labels in Grow a Garden trading chat (Huge / Titanic / Godly — and community Semi-Huge) are based on hatch weight at Age 1, not the big kg number after you AFK level. r/growagarden threads keep arguing ranges because the wiki uses different “class” language than Discord sellers. Use this pet weight calculator to recover hatch kg first, then match the table. Verified September 20, 2026.

Common community hatch-weight bands (Age 1 / reverse-hatch estimate). These are trading slang, not a Roblox-official table — always re-check live tooltips:

Community label	Typical hatch weight (Age 1)	What players mean
Small / normal	Under ~2 kg	Average egg rolls; fine for farming, lower trade premium
Large / Semi-Huge	~2–4.9 kg	Above average; “semi-huge” talk starts here for many sellers
Huge	~5–6.9 kg	High ability/stud scaling; strong trade demand
Semi-Titanic	~7–7.9 kg	Bridge tier used on Reddit/Discord sheets
Titanic	~8–8.9 kg (some say 7+)	Top-shelf hatch; aging makes card kg look huge
Godly / Colossal slang	~9 kg+ (some say 10+)	Rare hatch; “Colossal” is community slang for 10+

• Aging a 1.2 kg hatch to Age 100 (~12 kg on the card) does not turn it into a Huge hatch.
• Ostrich (and similar) helpers that hatch pets at higher ages inflate the card kg — reverse hatch weight before you flex “titanic.”
• After you know hatch kg, check demand on the pet value list and fairness on the trade calculator / WFL guide.

Pet size classes: Huge, Titanic, and Godly

Trade chat uses size-class language more than raw decimals. Community hatch-weight bands are approximate, always quote raw kg and age in offers:

Class	Approx. hatch weight (Wh)	Notes
Small	< 1 kg	Weak growth slope; hard to trade up
Normal	1 to 4.99 kg	Most common hatches
Huge	5 to 6.99 kg	Not the same as the HUGE modifier
Titanic	7 to 8.99 kg	Premium trade language
Godly	≥ 9 kg	Top hatch-weight band

Separately, a rare HUGE modifier (~0.1% on many hatch tables) can multiply hatch weight by about ×4. That roll is why some pets jump classes overnight. Do not confuse the HUGE modifier with the “Huge” class band name.

• Brontosaurus-style helpers can bump Wh before the pet exists.
• Ostrich-style age helpers raise A faster, which raises W through the formula.
• Shop, chest, and craft pets often use narrower Wh bands than egg pets, compare like with like.
• Value context: pet value list. Ability meta: pet tier list.

Plan target weight and the age you need

Direct answer: if you know hatch weight Wh and want card weight W, solve age with A ≈ (11 × W ÷ Wh) − 10. Example: Wh = 2.0 kg, target W = 12 kg → A ≈ (11×12÷2) − 10 = 56. At Age 100, expect about 10 × Wh. Use the calculator above to project the curve, then pet XP calculator for the grind. Verified September 20, 2026.

After you know the target age, switch to the pet XP calculator to estimate the grind — then re-check ability feel on the pet cooldown calculator.

You know	Solve for	Formula
Hatch Wh + age A	Current / future W	W ≈ (Wh ÷ 11) × (A + 10)
Current W + age A	Hatch Wh	Wh ≈ (11 × W) ÷ (A + 10)
Hatch Wh + target W	Age A to reach it	A ≈ (11 × W ÷ Wh) − 10

Tip: always state whether a kg number is hatch or current card weight. Mixing them is the #1 reason Reddit “is this Titanic?” posts get wrong answers.

XP needed to reach your target age

Aging costs increasing XP per level. Early ages sit in the tens or hundreds of XP; late ages climb into the hundreds of thousands. Age 50 and Age 100 are the milestones traders and AFK levelers talk about most. Use Pet XP Needed mode before you commit food, Capybara-style hunger support, or XP aura pets for a long grind.

• Keep hunger stable so XP pets actually tick.
• Stack XP auras (Starfish, Blood Owl, and current meta XP pets) while you AFK.
• Focus one meta pet to a milestone age before spreading XP thin across a zoo.
• Recalculate remaining XP after each big age jump, curves steepen.
• Fund eggs and food early with how to get Sheckles fast and the beginners guide.

Egg hatch time and helper pets

Hatch time falls when you equip hatch-speed pets and helpers. Base egg durations differ by egg tier (Common through Mythical, Bug, and event eggs). Egg Hatch Speed mode stacks helper bonuses so you can compare raw egg hours vs hours with Chicken + Kiwi + Rooster (and stronger variants). For egg pools and prices, use the eggs list and the dedicated egg hatch calculator.

Helper type	Role	Planning note
Chicken / Kiwi / Rooster family	Core hatch speed	Baseline AFK loadout
Blood Kiwi / Sunny-Side Chicken	Stronger hatch help	Meta when available
Bald Eagle and similar	Extra hatch support	Confirm live tooltip
Pet Incubator / gear	Slot bonus	Only count what you own

• Volume hatching multiplies the value of even small % speed gains.
• HUGE rolls stay rare, speed farming raises attempts, not the 0.1% itself.
• Egg shop timing: restock timer.

How weight scales pet abilities

Most pets express stronger passives or better trigger rates as weight rises. Many actives feel better as effective cooldown shrinks with kg. A minority of pets have flat or soft-capped stats, Triceratops-style designs show up in community notes as exceptions. Always read the ability tooltip.

Trigger Chance mode is for comparing a light copy vs a heavy copy of the same species before you spend weeks leveling the wrong one. Use it as a relative compare tool, not a PvP DPS simulator. Deeper cooldown curves: pet cooldown calculator.

Why weight matters for trading

Trade chat prices Huge / Titanic / Godly language. Farming cares about ability uptime, mutations, hatch speed, XP auras, crop helpers. Before you accept a “fair” pet offer, run both copies through this calculator, then sanity-check with the trade calculator, WFL guide, and how to trade.

Before you accept, look up the species on the pet value list, then run both sides through the trade calculator so the deal is Fair on paper, not just vibes.

Goal	What to calculate	Next step
Keep or vend a hatch	Wh class + projected age-100 kg	pet value list
AFK level plan	XP to target age	pet tier list
Egg factory	Hatch hours with helpers	egg hatch calculator
Ability uptime	Trigger / weight compare	cooldown calculator
Hit a Sheckles crop goal	Different tool (crops)	value to weight calculator
Crop money	Different tool	crop value calculator

What to check after you know the kg

Once the calculator shows hatch weight and class, most players need one of these next:

• Trade calculator — build both sides of the offer and read Win / Fair / Loss
• Pet value list — see demand for that species before you overpay for age
• Pet XP calculator — estimate how long the Age grind will take
• Pet cooldown calculator — see how kg changes ability timing
• Egg hatch calculator — plan the next hatch hours before AFK

New to trading windows? Skim how to trade and the WFL guide, then confirm fairness in the trade calculator.

Ostrich, Brontosaurus, and hatch helpers

Two helper archetypes show up next to this calculator constantly. Hatch-weight helpers (Brontosaurus is the famous example) try to raise Wh before the pet exists, that permanently steepens the growth line. Age helpers (Ostrich-style) push A up faster after hatch so you reach the same kg sooner.

Planning the next egg? Use the egg hatch calculator for hours, and the eggs list to pick which egg can roll a heavier hatch.

Practical order: if you are egg-hatching for trade flex, prioritize Wh (helpers + HUGE luck + high-range eggs). If you already own an elite Wh pet, prioritize XP and age efficiency. Titanic and Godly are mostly hatch-weight outcomes, age multiplies the seed; it does not turn a tiny Wh into a Godly class by grind alone.

Pros and cons of heavy hatch pets

Pros	Cons
Steeper lifelong kg growth	Elite Wh can be expensive or RNG-gated
Stronger weight-scaled abilities	Some pets ignore or soft-cap weight
Clearer Titanic / Godly trade talk	Age grind still required to show final kg
Better keep-or-vend decisions early	Shop/craft pets use different Wh bands

Quick answers

Does age affect hatch weight?

No. Age raises current weight from a fixed hatch weight. Wh is set at hatch (or by pre-hatch helpers); leveling does not rewrite the seed.

Can event pets exceed normal weight?

Event and Mega pets often use different starting Wh bands, but growth usually still follows the hatch→age model. Compare bands within the same acquisition path.

Which pet has the fastest hatch bonus?

Meta shifts with updates. Chicken, Kiwi, Rooster, Blood Kiwi, and Sunny-Side Chicken are the usual hatch-speed core, check current tooltips and stack what you own.

Should I age weak pets?

Only for collection, specific flat-stat pets, or cheap XP practice. For trades and ability uptime, put XP into high Wh copies of meta species first.

What is a good hatch weight?

Anything that lands you in Huge+ for a meta pet is strong. Titanic and Godly Wh command premiums. Below 1 kg Wh is usually a vend-or-reroll for competitive play.

Do shop pets follow the same formula?

Growth usually follows the same age curve, but shop/chest/craft Wh ranges are often narrower than egg pets. Do not price a shop pet like an egg Titanic without checking kg.

Can I use this calculator on mobile mid-trade?

Yes. Pin the page, open Weight Progression, enter both sides’ kg and age, then decide before the trade window closes.

What to remember

• Pet weight follows W ≈ (Wh ÷ 11) × (A + 10); age 100 ≈ 10× hatch weight.
• Hatch weight is the seed of lifelong kg, ability feel, and class language.
• Huge / Titanic / Godly are Wh bands; HUGE (×4 roll) is a separate rare modifier.
• Use XP mode before long AFK grinds; curves steepen hard late.
• Hatch helpers cut egg hours; Brontosaurus-style helpers raise Wh before hatch.
• Most abilities scale with weight, exceptions exist, so read tooltips.
• Never trade on class name alone; screenshot kg + age and run WFL.
• This tool is free in-browser; crop math belongs on the crop value calculator.

Mistakes that waste XP

• Confusing the HUGE modifier (×4 hatch) with the “Huge” class band in trade chat.
• Comparing shop-pet Wh ranges to egg-pet Wh ranges as if they were identical.
• Paying Age 50 prices for a pet with weak hatch weight.
• Applying crop Weight² formulas to pets, pets use the hatch/age model above.
• Ignoring flat-scaling pets when chasing kg premiums.
• Estimating egg hours without counting the helpers you will actually equip.
• Aging a zoo evenly instead of pushing one elite Wh meta pet to a milestone.
• Accepting trades without stating friend-server context when crops are also in the deal.

Tips that save grind time

• Screenshot Wh, age, and current kg together before every serious pet offer.
• If Wh is elite, prioritize Ostrich-style age helpers; if Wh is weak, hatch again instead of grinding.
• Run light vs heavy copies of the same species in Trigger Chance mode before buying XP food.
• Stack hatch-speed pets for volume eggs, more attempts beat waiting on one slow Mythical.
• After you know kg class, price demand on the pet value list and close with the trade calculator.

Final tips

Pet progress in Grow a Garden is easier when you separate three levers: the hatch weight you rolled, the age you still need, and the helpers that change either timer. The calculator on this page exists so you can project kilograms, remaining XP, egg hours, and trigger chance without guessing from Discord screenshots.

Start every keep-or-vend decision with Wh. Project age-100 weight, then decide whether the species is worth the grind on the tier list. When the offer is a trade, bring raw kg and age into the conversation and verify both sides with WFL tools, class nicknames alone hide bad deals.

For the wider farm loop, price crops on the crop value calculator, plan eggs with the egg hatch calculator, and keep learning from the guides hub and Grow a Garden Wiki. Scroll back to the tool, pick the mode that matches your question, and calculate before you commit Sheckles or sleep through another AFK session. Last Verified September 18, 2026.

Beanstalk event pets: check kg and age

Event pets from Beanstalk Part 2/3 are flooding trades. Before you pay “max” for a Beanstalk Bear, Chest Mimic, Cloud Hound, or Sheep, run hatch weight and age through this pet weight calculator.

Questions from kg, age 500, and pet calculator searches

These match how players type in Google — Age 500, base weight, pet size, and ability vs weight.

How much will my pet weigh at Age 500?

Use W ≈ (Wh ÷ 11) × 510, or about 46.36 × hatch weight. A 2 kg hatch projects near 92.7 kg at Age 500. In the calculator, set Max Age to 500 and enter hatch weight (or reverse from current kg + age first).

What is the Grow a Garden calculator for kg and age 500?

This pet weight calculator. Enter hatch weight (base weight) and set the target/max age to 500 to project card kg. Same community formula as Age 100 — only the age changes.

Is Age 500 the max pet age in Grow a Garden?

Community calculators and mid-2026 reports treat Age 500 as the long-grind cap. Older pages still say 100 or 125. Always match the Max Age field to what your live pet card allows after patches.

Is the Grow a Garden pet calculator the same as the pet weight calculator?

Yes on this site. “Pet calculator,” “GAG pet calculator,” and “pet weight calculator” all refer to this tool: kg by age, base/hatch weight reverse, ability trigger chance, XP, and hatch hours.

What is base weight on a Grow a Garden pet?

Base weight means hatch weight (Age-1 kg) — the seed that age multiplies. Recover it with Wh ≈ (11 × current kg) ÷ (age + 10) when you only know the card.

How do I use a base weight calculator for GAG pets?

Enter current kg and age in reverse mode (or Weight Progression after you recover Wh). That hatch/base kg is what traders use for Huge, Titanic, and Godly size talk.

Is there a Grow a Garden pet size calculator?

Yes — this page. Pet size class (Huge / Titanic / Godly) comes from hatch/base kg, not Age 500 kg. Recover hatch weight, then compare to community size bands below.

Should I use this page or the pet ability / cooldown calculator?

Use Ability Trigger Chance mode here for proc odds that scale with kg. Use the pet cooldown calculator for the cooldown timer (seconds between abilities). Weight Progression here still matters because heavier hatch kg usually feeds stronger ability feel.

Where is the Grow a Garden pet age calculator?

For kg at a target age (100 or 500), stay on Weight Progression here. For XP / time to reach that age, use XP mode or the pet XP calculator.

How do I calculate kg and age together?

Forward: enter hatch/base weight + age → get current or target kg. Reverse: enter current kg + age → get hatch/base weight. Formula W ≈ (Wh ÷ 11) × (A + 10).

Frequently asked questions

How do I find hatch weight if Ostrich leveled my pet?

Enter the current card kg and age into this pet weight calculator. It reverse-solves Wh ≈ (11 × W) ÷ (A + 10). Ostrich raises hatch age — it does not secretly add a Titanic hatch. Class is still the recovered Age-1 kg.

At what weight is a pet Huge, Titanic, or Godly?

Use hatch weight, not max aged kg. Community slang commonly treats ~5–6.9 kg hatch as Huge, ~8–8.9 kg as Titanic, and ~9 kg+ as Godly (some sheets call 10+ Colossal). Ranges differ by Discord — recover hatch kg first, then compare.

How do I calculate the age needed for a target pet weight?

With hatch weight Wh and target weight W: A ≈ (11 × W ÷ Wh) − 10. Or set target weight in planning mode above, then use the pet XP calculator to estimate grind time.

Does leveling to Age 100 change Huge or Titanic class?

No. Class talk is about hatch / Age-1 weight. Aging multiplies kg (~10× at Age 100) but does not upgrade a light hatch into a Huge hatch for trade labels.

Is heavier pet weight always better for abilities?

Heavier hatch weight usually means stronger ability radius / effect scaling at the same age — that is why Huge/Titanic hatches trade at a premium. Still check pet cooldown and live demand on the pet value list before paying for max age on a weak hatch.

What do Reddit players mean by pet scale?

Pet scale is slang for the kg-vs-age curve. This page is that tool: same as “GAG pet calculator” / pet weight. Formula W ≈ (Wh ÷ 11) × (A + 10).

What is pet scale in Grow a Garden?

Pet scale means how a pet’s kg grows with age from hatch weight. This pet weight calculator is the pet-scale tool: W ≈ (Wh ÷ 11) × (A + 10). Verified September 20, 2026.

Is a grow a garden pet calculator different from pet weight?

Usually no. “Pet calculator” searches land on weight/class tools. Start here for kg and Huge/Titanic/Godly, then use pet XP and pet mutations for leveling and shards.

What is Colossal vs Godly?

Community labels often call ~10 kg+ hatch weight Colossal. In-game class talk most players use stops at Godly (~9 kg+ hatch). Confirm thresholds in the class section above — do not invent a third official tier.

¿Sirve esta calculadora de pets de Grow a Garden (calculadora pets)?

Sí: es la misma calculadora de peso/edad (pet weight / pet scale). La interfaz está en inglés, pero la fórmula W ≈ (Wh ÷ 11) × (A + 10) es la que usan las guías de la comunidad.

How do I calculate hatch weight from current weight?

Use Wh ≈ (11 × Current Weight) ÷ (Age + 10). This estimates the original hatch weight before the pet gained kilograms through aging. Plug that Wh into Weight Progression mode to project age-50 or age-100 kg for trades.

Is heavier always better?

For most weight-scaled pets, yes, higher kg usually means stronger ability feel and higher trade premiums. A few pets use flat or soft-capped stats, so read the ability text before you pay a Titanic premium for a species that barely scales.

How much does a pet weigh at Age 100 vs Age 500?

Under the standard community formula, about ten times hatch weight (W ≈ 10 × Wh). A 1.2 kg hatch projects near 12 kg at age 100; a 7 kg Titanic hatch projects near 70 kg. Confirm live tooltips after patches.

What are Huge, Titanic, and Godly pets?

They are hatch-weight class bands used in trade chat: roughly Huge 5-6.99 kg Wh, Titanic 7-8.99 kg, Godly ≥ 9 kg. Band edges vary slightly by guide. Always screenshot raw kg and age, class names alone cause bad deals.

Does the HUGE hatch modifier equal the Huge class?

No. HUGE is a rare hatch multiplier (~0.1% on many tables, often ×4 Wh). “Huge” is a size-class band. A HUGE roll can push a pet into Titanic or Godly territory immediately.

Should I age a low hatch-weight pet to 100?

Only if the species is meta enough that ability identity beats class. Otherwise hatch better eggs or trade for a heavier copy of the same pet. Age multiplies Wh; it cannot invent a strong seed.

Does pet weight affect abilities in Grow a Garden?

Usually yes. Heavier pets tend to trigger more often or feel stronger on weight-scaled passives and actives. Exceptions exist. Compare two weights of the same species in Trigger Chance mode before you commit XP food.

Can I calculate egg hatch time here?

Yes, use Egg Hatch Speed mode with your helper pets. For egg pools, prices, and longer hatch planning, also open the egg hatch calculator and eggs list.

Is this a Grow a Garden 2 pet tool?
