Cosmic is the seventh rarity tier in Steal an Egg, and it is the wall almost every player hits on the way to end-game money. A single Cosmic pet earns between roughly $185K/s and $100M/s — hundreds to hundreds of thousands of times more than the Legendary pets that carried you through the early biomes. This guide lists every Cosmic pet in the game, its source and income, the best Cosmic pets to farm right now, and how to actually reach them.
Data below is from the live community pet indexes (Eldorado and stealanegg.dev), current as of Update #4 "Angels & Demons" (live 2026-09-13). Income values move whenever a new biome ships and mutations/size change the final number, so treat the tiers as the durable part and re-check exact figures in-game.
Quick answer: The best farmable Cosmic pets in Steal an Egg are Holy Peacock and Demon Hound at $25M/s each, from the Angels & Demons biome. The single highest-income Cosmic overall is Drilla at $100M/s, but Drilla is a limited event pet (Drill Egg, awarded to top-3 finishers in the Monster Obby during the Admin Abuse event) — you can't farm it from a biome. Cosmic sits above Mythic and below Secret, Eternal, and Divine, so a Cosmic is a huge step up from a Legendary, but the top earners in the game (Unicorn, ArchAngel, World Burner, Aetheron) are still one to three tiers higher.

Key Takeaways
- Cosmic is tier 7 of 10. The full ladder is Common → Uncommon → Rare → Epic → Legendary → Mythic → Cosmic → Secret → Eternal → Divine.
- Income range for Cosmic pets: ~$185K/s to $100M/s. The best you can actually farm are Holy Peacock and Demon Hound at $25M/s each (Angels & Demons biome). The highest-income Cosmic overall is the limited-event Drilla ($100M/s).
- Farmable Cosmic pets come from later biomes — Snow, Abyss Ocean, Prehistoric, Cosmic, Titan Temple, Cherry Blossom, and the Angels & Demons biome. A few Cosmics (Drilla, Nibbles #013) are limited event pets and can't be farmed.
- Steal an Egg has NO codes. Any site listing "Steal an Egg codes" is wrong; income boosts come from pets, Speed, and rebirths.
- Mutation and pet size change the final income — the numbers here are base income before those multipliers.
What is a Cosmic pet in Steal an Egg?
Steal an Egg is a steal-and-hatch pet-income sim: you steal eggs from guarded biome nests, carry them back to your pen, hatch them into pets, and those pets generate money per second forever. Money buys base upgrades and Speed, Speed unlocks heavier eggs and later biomes, and later biomes drop rarer pets. That loop is the whole game.
Every pet has a rarity, and rarity is the single biggest driver of income. The full ladder, in order:
Common → Uncommon → Rare → Epic → Legendary → Mythic → Cosmic → Secret → Eternal → Divine.
Cosmic is the seventh rung. It is the first tier where pets routinely clear six and seven figures per second, which is why hitting your first Cosmic feels like the game finally opening up. For context, the best Legendary in an early biome (Desert's Snake) earns $3.6K/s — a mid-Cosmic like Rhinotaur ($17.5M/s) out-earns it by roughly 4,800×.
Cosmic is not the top of the game, though. Above it sit Secret, Eternal, and Divine pets — the tier where the true best pets live (Kitsune at $1.8B/s, Unicorn at $1B/s, ArchAngel and World Burner at $5B/s, and the fusion-only Aetheron at $6.9B/s). Treat Cosmic as the reliable mid-to-late-game engine that funds the Speed you need to reach those.
All Cosmic pets in Steal an Egg (full list + income)
Below is every Cosmic-rarity pet in the current index (cross-checked against the Eldorado all-pets index and stealanegg.dev, both current to Update #4), grouped by where it comes from, with base income per second. Newer Angels & Demons Cosmics have confirmed income; a couple of limited-egg Cosmics are still gacha-only with income not yet published — those are flagged.
Top Cosmic pets by income
| Rank | Pet | Source | Base income |
|---|---|---|---|
| 1 | Drilla | Drill Egg — limited event (top-3 Monster Obby, Admin Abuse) | $100M/s |
| 2 | Holy Peacock | Angels & Demons (Light) — farmable | $25M/s |
| 2 | Demon Hound | Angels & Demons (Dark) — farmable | $25M/s |
| 4 | Rhinotaur | Titan Temple — farmable | $17.5M/s |
| 5 | Sacred Moth | Angels & Demons (Light) — farmable | $16M/s |
| 5 | Imp | Angels & Demons (Dark) — farmable | $16M/s |
| 7 | Koi | Cherry Blossom — farmable | $12M/s |
| 8 | Mantaris | Titan Temple — farmable | $11M/s |
| 9 | Shattered Ram | Rift pet (RNG hatch) | $8M/s |
| 10 | Snowy Owl | Cherry Blossom — farmable | $7.5M/s |
Drilla is the highest-income Cosmic but is limited/event-only. The best farmable Cosmics are Holy Peacock and Demon Hound at $25M/s.
Mid and lower Cosmic pets
| Pet | Source | Base income |
|---|---|---|
| La Vacca Saturno Saturnita | Cosmic biome | $2.2M/s |
| Dreadclaw | Rift pet (RNG hatch) | $2.2M/s |
| Bronto | Prehistoric biome | $1.5M/s |
| Triceratops | Prehistoric biome | $1.2M/s |
| Beluga Whale | Abyss Ocean biome | $850K/s |
| Whale Shark | Abyss Ocean biome | $700K/s |
| Ventinal | Rift pet (RNG hatch) | $585K/s |
| King Mammoth | Snow biome | $400K/s |
| Royal Sphinx | Desert biome | $280K/s |
| Leviathan | Lake biome | $220K/s |
| Nibbles #013 | Limited event (Dr. Scramble) | $185K/s |
These mid-tier figures are currently listed on the Eldorado index; income moves with updates and is further modified by mutation and size, so confirm the exact number on the pet's card in-game. Several other limited-egg Cosmics (Crawler and its Mecha variant, Abyss Shark, Cosmic Dragon, Cosmic Gorilla, Cosmic Gecko, Cosmic Skeleton Boss) drop from Robux Store eggs or event eggs and their exact income is not published in the index — never trust a third-party number for those without checking in-game.
Best Cosmic pets to farm right now
Not every Cosmic is worth chasing. Here is where to spend your Speed:
1. Holy Peacock / Demon Hound ($25M/s) — the best Cosmics you can actually farm, from the Angels & Demons biome (Update #4). The biome rotates nightly between an Angels (Light) form and a Demons (Darkness) form, so you can only farm one side per night — Holy Peacock on Light nights, Demon Hound on Dark nights. Both are far easier to obtain than the biome's Divine drops (ArchAngel and World Burner) and are excellent value for the Speed required.
2. Rhinotaur ($17.5M/s) and Mantaris ($11M/s) — the two Cosmics from the Titan Temple biome. If you already have ~7 billion Speed to reach Titan Temple, both are worth grabbing before you push for the Gorilla King (Eternal, $880M/s).
A note on Drilla ($100M/s): it out-earns every farmable Cosmic, but it is not something you can grind for. Drilla comes only from the limited Drill Egg, awarded to the top three players in the Monster Obby event during Admin Abuse. If you didn't place, you can't get it — so don't build your plan around it. The same goes for the event-only Nibbles #013.
Everything below ~$1M/s (Royal Sphinx, Leviathan, King Mammoth) is fine as an early Cosmic to get you over the hump, but replace it as soon as a higher biome opens up — the gap between a $280K/s Cosmic and a $25M/s farmable Cosmic is enormous.

How to actually reach Cosmic pets
Most Cosmic pets live in the later biomes, and the gate on every later biome is Speed, not luck (the exceptions are the limited event Cosmics like Drilla, which you can't grind for). The path:
- Grind Speed on the treadmill. Speed lets you carry heavier, rarer eggs and outrun the biome guardians. Higher biomes demand exponentially more Speed — the Angels & Demons biome requires 20 billion Speed to unlock all three of its variants, and Update #4 added a new higher treadmill tier specifically to help players reach it. As Eldorado's Angels & Demons breakdown puts it, the biome is "night-only" and "rotates nightly between an Angels (Light) form and a Demons (Darkness) form," so which Cosmic you can farm depends on the in-game time.
- Rebirth for permanent bonuses. Rebirthing resets progress for a permanent multiplier that compounds every run; it is the single biggest long-term income lever.
- Chase mutations and size. Both boost a pet's base income. Exact multipliers are not dev-published, so check the in-game UI rather than any outside "mutation value" chart.
- Reinvest into base upgrades so your money-per-second keeps climbing while you farm.
If you would rather skip the multi-day Speed grind and jump straight to a stacked pen, boosting services can shortcut the progression.

Cosmic vs the tiers above it
Once you have a few strong Cosmics, the next question is always "what's above this?" Here is how Cosmic stacks up against the higher tiers so you know what you're farming toward:
| Tier | Example pet | Base income |
|---|---|---|
| Cosmic (farmable) | Holy Peacock / Demon Hound | $25M/s |
| Cosmic (limited) | Drilla | $100M/s |
| Secret | Mutant Shark | $215M/s |
| Eternal | Eternal Lunar Dragon | $250M/s |
| Eternal | Gorilla King | $880M/s |
| Divine | Unicorn | $1B/s |
| Divine | Kitsune | $1.8B/s |
| Divine | ArchAngel / World Burner | $5B/s |
| Divine | Aetheron (fusion: ArchAngel + World Burner) | $6.9B/s |
The jump from your best farmable Cosmic (Holy Peacock, $25M/s) to the game's best Divine (Aetheron, $6.9B/s) is roughly 276× — which is exactly why players grind Cosmics as the engine that pays for the Speed to reach Eternals and Divines. Note that Aetheron isn't a biome drop at all: it's fused at the Secret Fusion Shrine inside Angels & Demons by combining an ArchAngel and a World Burner.
FAQ
What is the best Cosmic pet in Steal an Egg? By raw income, Drilla is the top Cosmic at $100M/s — but it's a limited event pet you can't farm. The best Cosmics you can actually obtain are Holy Peacock and Demon Hound, both $25M/s, from the Angels & Demons biome.
How many Cosmic pets are there in Steal an Egg? There are roughly two dozen Cosmic-rarity pets across the later biomes and limited eggs, ranging from about $185K/s up to Drilla at $100M/s. A few limited-egg and rift Cosmics have income that isn't fully published in the index yet.
Is Cosmic the rarest tier in Steal an Egg? No. Cosmic is the seventh of ten tiers. Above it are Secret, Eternal, and Divine — Divine holds the game's best pets, including Kitsune ($1.8B/s), Unicorn ($1B/s), and the fusion-only Aetheron ($6.9B/s).
How do I get Cosmic pets in Steal an Egg? Most Cosmic pets drop from the later biomes (Snow, Abyss Ocean, Prehistoric, Titan Temple, Cosmic, Cherry Blossom, and Angels & Demons). Reaching those biomes is gated by Speed, which you grind on the treadmill and boost permanently through rebirths — not by codes. A few Cosmics (Drilla, Nibbles #013) are limited event pets and can't be farmed at all.
Are there codes for free Cosmic pets? No. Steal an Egg has no codes and no codes menu. Income and rarity come entirely from stealing eggs, grinding Speed, rebirthing, and mutations.
Does mutation change a Cosmic pet's income? Yes. Mutations and pet size both increase base income, but the exact multipliers are not published by the developer — check the pet's card in the in-game UI for the real figure.
