Steal an Egg on Roblox runs on a simple but addictive loop: steal eggs from biomes, hatch them into pets, and watch those pets generate passive income you can funnel back into upgrades. The catch is that not all eggs are worth equal effort. A Chicken from the Forest biome earns $1 per second. A Mammoth from Snow earns $42,000 per second. Knowing the full picture before you commit to a grind saves a lot of wasted runs.
How many eggs and pets are in Steal an Egg?
There are currently 78 egg pets spread across multiple biomes. Some of these are only obtainable through limited-time eggs, which means the window to collect certain pets can close without warning. The breakdown covers everything from common Forest pets to Cosmic-tier giants in the Snow and Abyss Ocean biomes.
Rarity tiers run from Common at the bottom through Uncommon, Rare, Epic, Legendary, Mythic, Cosmic, and finally Secret at the very top. Income scales dramatically with rarity, so the difference between a Legendary and a Mythic is not just a cosmetic step up.

What are the best pets to target for income?
After running the numbers across all biomes, the income ceiling sits with Bronto at $1,500,000 per second from the Prehistoric biome, Beluga Whale at $850,000 per second from Abyss Ocean, and Whale Shark at $700,000 per second. King Mammoth from Snow at $400,000 per second is more accessible than the Prehistoric pets but still requires serious progression.
For mid-game players who have not unlocked the top biomes yet, the Volcano biome offers the best return on effort outside of Secret tier. Lava Iguana at $11,000 per second and Flaming Bull at $9,500 per second are both Legendary rarity, which means they are grindable without needing perfect luck.

The Jungle biome deserves mention for mid-game efficiency. Spider (Mythic, $22,000/s) and Orangutini Ananassini (Legendary, $5,500/s) give you two strong targets without needing to reach the Snow or Volcano biomes first.
How does rarity affect income in Steal an Egg?
The income jump between rarity tiers is not linear. Common pets top out at $6 per second (Jerboa). Mythic pets start at $16,000 per second (Sand Spider) and go up to $120,000 per second (Ankylosaurus). That is roughly a 2,700x difference between the floor of Common and the floor of Mythic.
Cosmic tier starts at $400,000 per second and caps at $1,500,000 per second based on current data. Secret tier sits entirely in its own category with Cerberus at $8,000,000 per second, which is more than 5x the highest Cosmic pet.
Tips for completing the full egg index
Completing the full 78-pet index is a long-term goal, but a few habits make it much more manageable:
- Prioritize movement speed upgrades. Faster movement means more eggs stolen per run, which directly increases your chances of hitting rarer eggs.
- Target high-income biomes early. Even a single Legendary pet from Jungle or Volcano will accelerate your upgrade pace significantly compared to farming Forest pets.
- Track limited-time eggs. Some pets are only available through limited eggs. Missing these means a permanent gap in your index, so stay current on what is active.
- Stack Mythic pets before chasing Cosmic. The income gap between Mythic and Cosmic is large, but so is the difficulty gap. Build a stable Mythic income base first.
