The Roblox description of Steal Animal Egg tells you to discover cute eggs, sizes, and mutations. It does not publish a mutation list, drop rates, or a rule that a larger model earns more.
Three different questions
| Question | What answers it |
|---|---|
| Does it look different? | Size, glow, or other effects you can see |
| Did the game name a property? | The text on the pet or egg |
| Is it earning? | The income label and whether best selection keeps it |
A glow is not a named mutation until the interface names one. A large model is not a multiplier until a label says so. Gameplay shows best selection skipping a larger-looking pet, so appearance is a clue to inspect, not the sort key.
The thumbnail labels
The official promotional image prints two examples side by side: a Common Cat at $3/s and a Divine Geek Cat at $847Q/s. Those strings are on the artwork. They are not a hatch table, and they do not say which egg produces either cat. Both pets are recorded under Pets with that limit written on the entry.
Passes do not say they change the pool
x2 Growth advertises faster growth for planted eggs. x2 Cash advertises double yard-pet money. Neither description mentions mutation chance or a better size. A bundle can include a named pet, such as Fire Dragon or the UNIVERSAL Pet, without stating that pet's income.
If you are deciding whether to sell an odd-looking pet, read its label, the sale offer, and your free yard slots first. The checklist is in Hatch, Equip, and Sell.
