Pets Guide

Hatched pets earn money in your garden, fill the Index for free rewards, and fuse into stronger versions when you have three of the same type.

Steal An Egg pets guide: garden pens earning cash, Pet Index claims, and Fuse duplicates into stronger pets

Hatched pets earn money every second in your pens. New species fill the Index for one-time claims, and three of the same type can go into Fuse. Size and rarity are separate, a huge common is not automatically better than a small Secret.

Better eggs come from steals in biomes your Speed can reach. Unsure which nest is safe? Steal Check reads your Speed against gates and egg weight. The beginner guide covers the first Index claim.

Rift pets

Use the Rift Machine in the lobby. Feed it the three pets it currently asks for to receive a Riftborn Egg, Riftbeasts Egg, or Shattered Rift Egg. Those eggs hatch the fifteen exclusive Rift pets below. Hatch chances are per egg pool roll, not a single shared table across all three eggs.

Angels & Demons

Angels & Demons is the twelfth biome. It only appears at night and needs about 20B Speed on the gate. Each night it rolls Angels (Light pets), Demons (Darkness pets), or a rare Merged form with both egg pools plus a luck boost.

  • Train to roughly 20B Speed before you commit. The gate applies to Angels, Demons, and Merged alike
  • Wait for in-game night. The zone is closed during day
  • Check which variant spawned before you steal. Angels and Demons each keep their own eight-pet Index lines
  • If Merged is up, prioritize eggs while the luck bonus is live instead of saving the run for later
  • Guardians change with the variant. Build return buffer the same way you would for Titan Temple

Gate and egg-weight targets are on the speed page. Light and Dark Index rows are in the biome table above.

Secret Fusion Shrine

A Secret Fusion Shrine is behind the waterfall inside Angels & Demons. Eligible Eternal or Divine Light and Dark pets from this biome go on the pedestals and return a Fusion Egg for your pens.

  1. Enter Angels & Demons at night with enough Speed to steal and return
  2. Find the waterfall and walk the hidden path behind it into the portal (Demons nights may use a lava-wall entrance instead)
  3. Place one eligible Light pet and one eligible Dark pet on the pedestals
  4. Only Eternal or Divine pets from this biome's Light or Dark lines qualify. Older-biome Eternals and Divines are rejected
  5. Collect the Fusion Egg, park it in a free pen, and hatch the fused pet

Light vs Dark ring event (archive)

During the Sep 12–13 launch window, a limited Light vs Dark team event ran alongside the biome. Players picked a side, collected rings on a timer, and chased milestone rewards. That ring loop is archive unless it returns in a later Admin Abuse.

  • Pick Light or Dark when the prompt appears, then keep moving for rings instead of camping one nest
  • Temporary wings or magnet buffs help clear distance between ring clusters
  • Rough launch-window milestones were about ~800 rings for a mutated egg roll and ~1,500 for the top reward tier. Use the live meter if the event returns

When is Angels & Demons open?

Only at night. During the day the zone stays closed even if you already have 20B Speed.

What is the Merged biome?

A rare night roll where Angels and Demons share the same map. Both egg pools appear and a luck bonus is active while it lasts. Steal while it is up.

Which pets can enter the Fusion Shrine?

Eternal or Divine pets from this biome's Light or Dark lines: Pegasus, ArchAngel, Skeleton Horse, and World Burner. Pets from Forest through Titan Temple do not qualify.

Do I need both sides to finish the Index?

Yes. Eight Light pets and eight Darkness pets means logging in across multiple nights until you have seen both variants (or a Merged night).

Luminous Egg & Monster Egg archive

Luminous Egg is the current Robux shop replacement for Monster Egg. Each hatch rolls one of six pets below. Separately, a Luminous re-roll can turn any of those results into a Luminous variant. Base incomes below are not locked yet; trust the in-game Index after hatch.

Rarity order

UI text color changes by tier. Longer hatch timers on map eggs usually pair with higher rarities.

Common → Uncommon → Rare → Epic → Legendary → Mythic → Cosmic → Secret → Eternal → Divine

Pet Index

  1. Hatch or steal an egg until a new pet species appears
  2. Open Pet Index on the left side of the screen
  3. Tap Claim on any glowing entry for cash, traps, Speed, or other rewards
  4. Fill every species slot in a biome to unlock that zone's exclusive bat skin, stronger knockback when you hit egg carriers
  5. Repeat after every new species. Missing claims means free items sitting uncollected

Fuse machine

  • Feed three pets of the same type into the Fuse machine
  • Gold and silver variants count as the same type as the base species
  • Higher-quality inputs improve fuse luck. Do not fuse your weakest three commons if you have one strong donor
  • Output can be a stronger pet or sometimes an egg. Read the preview before you confirm
  • Fusing frees pen slots compared to hoarding duplicates
  • Do not fuse Rainbow, Spirit Bloom, Fractured, Monstrous, Mecha, Luminous, or other mutated pets you want to keep. The output can drop the mutation

Pen management

  • Upgrade pens when the UI blocks new placements
  • Use Sell All or remove weak pets before a rare hatch
  • Equip Best puts your strongest income pets active without manual sorting
  • Offline hatch keeps timers running. Pick up eggs when you return
  • Nighttime speeds up hatch for eggs already in garden pens

All mutations and multipliers

Mutations multiply a pet's pen income on top of its base rate and any size roll. Map eggs can hatch with Silver, Golden, or Rainbow. Bloom and Spirit Bloom come from the Sakura Incubator in Cherry Blossom. Fractured comes from the Boss Shop after Rift Overlord fights. Monstrous is a limited mutation on Titan Temple pets from Hungry Frog Monster Chests (Aug 29 to Sep 5, 2026). Mecha is a rare hatch variant on the retired Monster Egg. Luminous is the rare visual roll on the current Luminous Egg shop purchase.

  • Spirit Bloom is the highest permanent incubator multiplier. Charge Sakura eggs to 150% when you are chasing it
  • Silver, Golden, or Rainbow eggs can still enter the Sakura Incubator; Bloom or Spirit Bloom can stack on that roll
  • Fractured is bought with Boss Tokens after clearing map Rifts, not rolled from Sakura or map nests
  • Monstrous only applies to Titan Temple pets and came from the limited Hungry Frog event (Aug 29 to Sep 5, 2026)
  • Mecha came from Monster Egg hatches before that shop egg was retired. Luminous Egg is the current shop replacement
  • Do not fuse pets carrying Rainbow, Spirit Bloom, Fractured, Monstrous, Mecha, or Luminous unless you accept losing the variant on the output
  • A mutated pet from a mid-tier species can out-earn a plain pet from a higher rarity

Money route by stage

Pen income per second is the engine for every upgrade. Steal eggs from the farthest biome you can return from, hatch, Equip Best, then reinvest before you push farther.

When a stage jumps biomes, check the new gate and egg weight in Steal Check so income upgrades are not wasted on failed returns. Full Speed tables stay on the speed guide.

Sakura Incubator

The Sakura Incubator sits at the back of Cherry Blossom. Offer a Crane pet once to unlock it permanently, then charge inventory eggs with Sakura Crystals from the Great Bloom event for Bloom or Spirit Bloom mutations.

Unlock steps

  1. Hatch a Crane from a Cherry Blossom nest egg (plan for about 3.5B Speed on the steal, above the 2.5B gate readout)
  2. Carry the Crane to the Sakura Incubator at the end of the zone
  3. Submit the Crane, the unlock is permanent, but that pet is consumed
  4. Hatch another Crane later if you need a fresh one; size and mutations on the offer do not matter

Great Bloom event

  • Runs on server time every 30 minutes in Cherry Blossom
  • Lasts about three minutes, stay in-zone before the notification so you do not waste travel time
  • After unlock, a timer above the Sakura Incubator shows when the next Great Bloom starts
  • Crystal Cherry Blossom Trees spawn; equip your bat and hit them for Sakura Crystals
  • Farm crystals during the window; you need a large stack before mutating high-tier eggs

Mutating eggs

  • Place an egg from your inventory into the unlocked Incubator (hatched pets cannot be mutated here)
  • Eggs that already show Silver, Golden, or Rainbow can still go in; Bloom or Spirit Bloom can stack on top of that regular mutation
  • Deposit Sakura Crystals to fill the charge meter
  • At 100% charge the egg mutates, about 97.5% Bloom, 2.5% Spirit Bloom on that roll
  • Charge to 150% (max) when you are hunting Spirit Bloom; higher charge improves the rare outcome but does not guarantee it
  • Roughly 1,000 crystals fills a 100% charge on many eggs; watch the meter before you commit
MutationDetail
BloomCommon Sakura mutation from the Incubator; boosts egg value on hatch
Spirit BloomRare Incubator mutation (~2.5% at 100% charge); chase at 150% charge

Do I lose my Crane after unlocking the Incubator?

Yes. The Crane is consumed when you submit it. The machine stays unlocked forever, hatch another Cherry Blossom egg when you need a replacement.

Can I mutate eggs already in my garden pens?

No. Pull the egg into your inventory first, then load it into the Sakura Incubator. Mutations apply before you hatch.

How often is Great Bloom?

About every 30 minutes on server time, with a three-minute crystal farming window. After you unlock the Incubator, read the timer above the machine for the next start, and wait in Cherry Blossom before the alert so you can bat trees immediately.

Can I Sakura-mutate an egg that already has Silver, Golden, or Rainbow?

Yes. Load that unhatched egg into the Incubator as usual. Bloom or Spirit Bloom can apply on top of the regular mutation you already see on the shell.

FAQ

Does bigger always mean more income?

Not always. Size (shown in kg on some pets) affects carry weight when the pet is still an egg and how huge they look on base. Base income comes from the Index rate plus any size or mutation roll. Check the toast when a hatch finishes.

Why does my hatch toast pay more than this table?

This page lists pen income per second, not the one-time Speed and cash from Index claims. A Bear shows $240/s here but its first-time claim can still pay $24k. Huge or mutated hatches also roll above the base rate.

What are silver and gold variants?

Same species with alternate colors or eyes. They count for Index and Fuse as the base type, but can look different in pens.

How much does skip hatch cost?

Short skips show around 9 Robux on quick timers; multi-hour eggs scale higher. Only skip when the pet is worth more than the Robux you are spending.

Do Index rewards include Speed?

Yes. The first time you hatch a new species, the Index entry pays Speed and cash on top of traps or other one-time items. Claim after every hatch so nothing sits uncollected.

What do I get for completing a biome Index?

Filling a zone's Index pays bonus Speed and cash plus an exclusive bat skin with stronger knockback. Most biomes have eight pets; Angels & Demons has sixteen (eight Light and eight Dark across night rolls).

How many pets are in the Index?

About 140 Index entries when you count 104 biome pets plus limited Event, Rift, Brain Rot, Monster archive, Mecha, Fusion, and Luminous lines. Saturday updates can add more.

What is the highest income pet?

Aetheron (Divine, Fusion Shrine) leads locked base rates at $6.9B/s. ArchAngel and World Burner follow at $5B/s, then Shattered Colossus at $3.5B/s. Size and mutation still change what you actually earn.

How do I get Rift pets?

Open the Rift Machine in the lobby, hand over the three pets it asks for, and hatch the Riftborn, Riftbeasts, or Shattered Rift Egg you receive. Map Rifts every ~30 minutes are a separate Overlord fight path for Boss Tokens and the Boss Shop.

How do I get Angels & Demons pets?

Reach about 20B Speed, enter the night-only twelfth biome, and steal from whichever Angels or Demons variant is up. Merged nights share both pools. Eternal and Divine Light or Dark pets can also feed the Fusion Shrine for Equinox ($1.8B/s) and Aetheron ($6.9B/s).

What happened to the Monster Egg?

It was retired in the Sep 12 update and replaced by Luminous Egg in the Robux shop. Existing Monster and Mecha pets stay. The archive table on this page lists the old six-monster pool.

What is the Luminous Egg?

The current Robux shop egg that replaced Monster Egg. It rolls Spike, Spirit Manta, Abyss Shark, Electric Eel, Terra Snapper, or Cthulhu, with a rare Luminous visual re-roll on top.

What is the Monster Egg?

A retired Robux shop egg with six monster species and a rare Mecha variant roll. It is not the same as stealing Titan Temple zone eggs or opening Hungry Frog Monster Chests from the Aug 29 to Sep 5 event.

Can you trade pets?

Not yet. There is no built-in trade UI. Expect that to change later; until then, Index completion and Fuse are the free progression path.

Is there an official tier list?

No ranked list from the developers. Sort by income per second, fuse upgrades, and Index completion instead of chasing a static S-tier chart.
