As you charge and run through the areas, you’ll see one or more mutation icons pop up on your screen. To get a mutated brainrot, you must click/tap on that button before it disappears. Click/tap on it successfully, and the brainrot you get from the lucky block will have the respective mutation. If you fail to click on it on time, you’ll miss out on the mutation.
Be Flash for Brainrots has 9 mutations. Four out of these - Gold, Diamond, Rainbow, and Horizon - can spawn naturally, while the other five - Candy, Lava, Blizzard, Lightning, and Hacker - can only be obtained during their specific events.
Events in Be Flash for Brainrots happen randomly and last for 10 minutes, giving you plenty of time to collect brainrots with mutations. If you want to spawn a specific event, you can do so by interacting with the events podium to the left of the leaderboards. It will cost you Robux, though.
