Pets Guide

Best pets by income

Top base incomes after Update #6. Size and mutation still change what pens pay.

All pets and income

One hundred four biome pets from Forest through Angels & Demons, plus limited Event, Rift, Brain Rot, Monster Egg archive, Fusion, and Luminous shop pools below. Income is pen $/s before size and mutation rolls. Index reward is the one-time Speed and cash claim when you first unlock that species.

Pets by biome

Species grouped by the biome where their eggs appear.

Make sure the zone is reachable with Steal Check before you camp a late-biome nest for Index fills.

Event pets

Limited event pets that are not on a biome nest table. Drilla comes from Admin Abuse Drill Eggs. Experiment Shop pets are Update #5 Samples buys. Boss Mastery and Mecha Scrambler come from Update #6 Mech fights. Extinction Egg pets sit in their own section below.

Rift pets

Update #6 replaced the lobby Rift trade-in with Dr. Scramble's Lab. The fifteen Rift pets below remain Index reference for eggs you already hatched. Map Rifts for Overlord fights can still appear.

Brain Rot shop pets

Brain Rot Eggs are Robux shop purchases, not biome nest steals. Hatch chances below are fixed for that limited egg. A dash means no base income is listed for that row yet.

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 sits behind the middle waterfall on the left side of Angels & Demons. The wall reads as water or lava depending on the night's Angels or Demons roll. Walk into the falls, wait a beat for the teleport, then use the pedestals.

1. Enter Angels & Demons at night. You can reach the shrine portal even if your Speed is short of a full egg steal, but you still need Eternal or Divine Light and Dark pets to fuse
2. Find the middle waterfall on the left and walk straight into it. Water or lava skin depends on the night variant; after a short pause the screen darkens and you teleport to the shrine
3. Place one eligible Light pet and one eligible Dark pet on the pedestals. You can run both sides yourself or split the pair with another player
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

Fusion pairs

Fusion pets

Fusion Shrine pets hatch from Fusion Eggs made inside Angels & Demons. They are not map-nest steals. Equinox comes from Eternal Light + Dark inputs; Aetheron from Divine Light + Dark inputs.

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
• Launch-window milestones sat around ~800 rings for a mutated egg roll and ~1,500 for the top reward tier

Extinction Egg

Update #6 Featured Robux egg (bundles 99 / 249 / 799 / 3,499 Robux; sale through about October 10, 2026). Six extinct animals; about 1% of hatches also roll a Skeletal variant. Does not feed Lab pity or Boss Mastery.

Skeletal variants

About 1% of Extinction Egg hatches also roll the Skeletal visual on whichever extinct pet you got. Skeletal Sabertooth pays $9B/s.

Luminous Egg & Monster Egg archive

Luminous Egg replaced Monster Egg on Sep 12. Update #6 put Extinction Egg in Featured Premium. Luminous packs commonly list 99 / 249 / 799 / 3,499 Robux.

Luminous variants

About 1% of Luminous Egg hatches also roll the Luminous visual on whichever pet you got. Same rarity tier as the base pet.

Monster Egg archive

Monster Eggs were retired from the Robux shop in the Sep 12 Angels & Demons update and replaced by Luminous Egg. Older pack prices matched Luminous (about 99 / 249 / 799 / 3,499 Robux). Keep this table as an archive for Mecha and Monster Egg hatches you already own. Mecha is not the same as the limited Monstrous mutation from Hungry Frog Monster Chests (Aug 29 to Sep 5, 2026).

Mecha variants

About 1% of Monster Egg hatches also roll Mecha armor on whichever monster you got. Same rarity tier as the base monster.

Hungry Frog Monster Chests could also roll a Monstrous Egg during the Aug 29 to Sep 5 window. That reward is separate from buying Monster Eggs in the shop. See the stealing guide archive.

Pet labels

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

• The Fuse machine is on the left side of the starting area, before you enter the biomes
• 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 for Silver, Gold, and Rainbow. 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, Sakura Bloom, Fractured, Scrambled, Monstrous, Mecha, Luminous, or other mutated pets you want to keep. The output can drop the mutation

Featured eggs

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

Mutations

Silver, Gold, Rainbow, Bloom, Sakura Bloom, Fractured, Scrambled, Monstrous, and Luminous multipliers, plus the Sakura Incubator, now live on the mutations guide.

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.
