The Yin Yang mutation gives affected Brainrots a 7.5x multiplier and the iconic black and white color theme resembling the Taijitu symbol. This makes it the best limited-time mutation we've seen so far, surpassing even the Galaxy mutation's 6x multiplier.
During the event, any Brainrot on the conveyor belt has a chance to spawn with the Yin Yang mutation. Brainrots with this mutation will be extremely valuable, both for their massive income boost and their collector's value after the event ends.
The Yin Yang mutation functions similarly to previous event mutations but with enhanced benefits:
Every hour during the event, players get access to the exclusive Yin & Yang Wheel. This wheel provides chances to win:
The wheel resets hourly, giving dedicated players multiple chances throughout the event to collect exclusive rewards. Based on previous event patterns, you get one free spin per hour when you're actively playing, with additional spins available for Robux.
Toiletto Focaccino is a Mythic rarity Brainrot releasing on September 27th, 2025, at 3PM EST. While the exact appearance hasn't been fully revealed, the name suggests it will be a toilet-themed character, following the game's tradition of bizarre and humorous designs.
