Steal an Egg Mutations & Sizes: Golden, Silver, Rainbow, Shiny, Huge
Mutations seen in-game
| Mutation | Where it shows up |
|---|---|
| Golden | Common early — Golden Chicken, Golden Bear, Golden Ice Dragon all seen |
| Silver | Silver Tung Tung Sahur (Brainrot egg), Silver Bear |
| Rainbow | ”Rainbow super rare” eggs in Prehistoric/Cosmic; Eternal Rainbow Mosasaurus |
| Shiny | Cosmic and late-game hatches |
A mutated egg is usually visible in the nest before you grab it (the shell colour changes), so they are worth a detour when the route is safe. Exact multipliers are not published; compare the card.
Size and “Huge”
Every pet and egg has a size, displayed as a weight (kg). Normal rolls are the baseline; “huge” and “massive” rolls can be taller than the player and pay many times more — one late-game clip shows a Kraken “you can’t even see the top of” as the team’s second-best earner, and an Eternal Ice Dragon near 1B/s on a large roll. The official description lists Huge alongside the top rarities because it is that important.
Why this matters for your base
- A Huge or Rainbow Legendary can out-earn a small Secret — always read money per second (pet list).
- Keep duplicates of a pet you like: three copies go into the fuse machine.
- Give away small spares rather than deleting them (how to give pets).
Update 1
Community reports say Update 1 (expected 22 August) expands the mutation pool and adds weather events that may influence spawns. We will list new mutations here once seen on screen — update log. Scripts advertising a “mutation selector” or “pet spawner” are exploits, not features.
Thanks for the feedback!
