Steal a Brainrot Rainbow Mutation

SAB Rainbow Mutation Available for Purchase

Rainbow Mutation is the top-tier mutation in Steal a Brainrot, offering a 10x income multiplier to any Brainrot it affects. This mutation gives Brainrots a vivid rainbow appearance with shimmering effects that cycle through various colors. It significantly outclasses all other mutations, including Gold (1.25x), Diamond (1.5x), Bloodrot (2x), Candy (4x), Lava (6x), and Radioactive (8.5x).

Rainbow Mutation can be obtained naturally from the conveyor belt with an extremely low spawn rate, or through the Rainbow Event, where spawn chances increase 10 times. Players trigger the Rainbow Event by feeding 25 Golden Brainrots into the Rainbow Machine, or by paying 299 Robux for instant activation. During the event, a giant rainbow beam strikes the conveyor belt entrance and increases Rainbow Mutation spawn rates for all incoming Brainrots.

About Rainbow Mutation

Rainbow Mutation represents the ultimate income Boost in the game. Each Brainrot can only possess one Mutation, making Rainbow the most sought-after variant for high-value units. The combination of Rainbow Mutation with the Strawberry trait (8x multiplier) creates the rarest trait and Mutation combo in the game, as both have extremely low natural occurrence rates, and a Strawberry Elephant must spawn simultaneously to trigger the Strawberry trait.

Completing the Rainbow index by collecting all Rainbow-mutated Brainrots provides a permanent 0.5x money multiplier that stacks with other completed indexes. Players also receive a rainbow-colored base as a visual reward for finishing the index. The mutation is especially valuable on Secret-rarity Brainrots, where the 10x multiplier can generate billions per second. Rainbow-mutated Brainrots count towards index progression and are prime targets for theft on public servers.
