Fake an Egg mutations

Last checked 2026-10-28

Fake an Egg mutations are not the same system as Steal an Egg mutations. The official icon advertises offline mutation (single official source). Public guides name Gold, Diamond, and Rainbow, but do not publish reliable odds or one shared income multiplier.

Mutation labels; blank numeric cells mean unknown.

What is known

  • A toast example: Your Llama egg mutated to Gold (AllThingsHow, 2026-10-19).
  • Fuse, three pets into one, can also roll a mutation (Roonby, 2026-10-26).
  • Mutations sit on the egg or pet. Weather traits are separate and come from events.
  • I found no source that says mutations stack. I am not adding that rule.

Weather traits, two lists

Roonby: October 26. AllThingsHow pets guide: October 19. Do not assume different names are equivalent.

Weather can arrive on its own or from a Weather Machine bought with Robux. robloxdatabase.com lists nine prices from 29 to 99 Robux. AllThingsHow only mentioned 29. I am not averaging them. The other game's mutation chart is explained on Fake an Egg vs Steal an Egg.

Questions

Are Steal an Egg multipliers the same?

No. That is a different game. See the comparison; its mutation figures are not Fake an Egg values.

Sources and check date

Last checked: 2026-10-28 (Asia/Singapore). A publisher's multiple articles and a video with its write-up count as one source, not independent confirmation. Historical snapshots retain their original dates. “Verified” requires two independent sources; official-only figures are labeled as such.
