What is a mutation?
A mutation is a visual + value modifier randomly applied to a pet. The Secrets guide breaks down the bread-and-butter ones: Golden and Silver are the common value multipliers, and Rainbow is the rare, high-value tier everyone hunts.
Do mutations stack?
Yes. The Secrets guide shows pets can carry multiple mutations at once (e.g. golden + silver on the same pet), and stacking is how you maximize sale value on the market. Rainbow typically sits on top as the headline modifier.
Where do they come from?
- Random on hatch / growth: most mutations appear by luck as pets hatch or mature in the Garden.
- Event boosts: Admin Abuse events and update windows are reported to spike mutation rates β be hatching during those.
- Limited / Brainrot pets: special event mutations (community-named examples like Strawberry Elephant and Bananita Dolphinita) show up only during limited windows and are covered on our pet tier list.
Value & strategy
Mutations multiply a pet's sell price and trading clout, so a mutated common can out-value a bare legendary. Bank mutations before trading on our pet index. Exact multipliers are community-observed β confirm in-game before pricing a trade.

EXPOSING all hidden SECRETS in Steal an Egg (Roblox) - legit tips

Community "secrets" breakdown β bat skins, server-shared egg spawns, the Fuse Machine luck mechanic, stacked mutations and the night 30x hatch bonus. (Only legit tips; exploit glitches not recommended.)
- Finishing each biomeβs Index unlocks a bat skin; higher-tier skins knock rival players much farther β useful for defending eggs you are carrying.
- All active servers share the same egg spawns but the SIZE differs per server β server-hop to find the biggest version of a rare egg before you collect it (collecting removes it everywhere until respawn).
- Fusing 3 of the same pet does NOT make a bigger pet β it gives an egg with higher LUCK (better roll odds), so fuse duplicates you do not need.
- Pets can stack MULTIPLE mutations (e.g. golden + silver) β pure luck, but it happens.
- At night your eggs get a ~30x growth multiplier on each ~4-5 min cycle; AFK through the night to hatch far faster than waiting offline. Empty-server trick: sort by fewest players and scroll past page one.
