All Steal An Egg pets

The scale of the income curve

Reported base rates vary substantially: Chicken is listed at $1/s, while Kitsune is listed at$1.8B/s. These endpoints describe the known-income sample, not the complete game or the return from an average egg.

When pen space is full, compare the actual per-second rates of the pet being replaced and the candidate, including their current variants. Rarity alone does not settle that comparison. Keep collection goals and event requirements in mind before selling a pet; a higher biome does not guarantee a high-income hatch. The income calculatorcan compare the rates and assumptions for pets you already own.

Rarity tiers

Tiers overlap in practice — a Legendary from a late biome out-earns a Mythic from an early one — which is why sorting by income rather than rarity is usually the more useful view. The tier list ranks purely on earnings.

Pets FAQ

How many pets are in Steal An Egg?

This database lists 115, covering 12 listed biomes plus limited egg, Experiment Shop and Boss Mastery records. This is the documented roster here, not a live count of every item in the game.

What is the highest income pet?

Kitsune has the highest numerical base-income entry in this dataset at $1.8B/s. Pets with unknown income are excluded, so this is not a claim about the strongest pet in the entire game.

What are the newest pets documented here?

The current additions are Eye Bat #021, Citadel Snail #007, Uncoiled Armadillo, recorded as Boss Mastery rewards from Dr. Scramble’s Revenge. They are claimed through the Mastery menu, not hatched in a biome. Their names, rarities and reward source have corroborating guides, but comparable base incomes remain unknown. See the update log for the dated research.

Can you trade pets in Steal An Egg?

There is no trade window in the game. Players can give pets and eggs directly to each other, which functions as two separate gifts rather than a protected trade, so there is no escrow to fall back on if the other person walks away.

What are the rarities in order?

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