Plants vs Brainrots is a Roblox experience where you can grow plants to destroy the brainrots and get more money. There is a Mutation Machine added as a part of the Merge Madness update. The mutation machine provides mutations of the brainrots and plants, which in turn increase the cash flow or deal more damage in Plants vs Brainrots.
At the same time, it gives you free rewards along with the high-value mutated brainrots or plants. So, to help you with that, here’s a complete guide on how to know about Mutation Machine in Plants vs Brainrots.
How to Use Mutation Machine in Plants vs Brainrots

The mutation machine works similarly to the fuse machine in Plants vs Brainrots. The mutation machine is located on the centre island, which you can reach by taking the mirror at your base. Once there, walk toward the machine and hold the mutated brainrots or plants you want to merge. Press the E key to put them inside.
After that, go near the EXP machine on the left side and use any EXP items, like a potion or a vial. This will power up the machine and start the mutation merger. If you use a frozen plant or brainrot with a neon plant or brainrot, it will make the frozen neon version of it.
Remember, you must use the same type of plants or brainrots with different mutations. The timer of mutation depends on the rarity of the brainrot. However, the mutation merging speeds up during the mutation mania weather event in Plants vs Brainrots. During this event, the mutation machine runs at a 2x speed.
