How to Find the Mutation Machine in Plants vs Brainrots
Just like any other machine that has been released in the game, the Mutation Machine sits on the Central Island in the game. To get there, you need to go to your base first and use the transparent door next to your garden. Once you walk through the door, you will spawn on the center island.
Go straight, and you will spot the huge Mutation Machine in the middle area. It has two pods labeled Mutation 1 and Mutation 2, where you place your plants or brainrots. On the left side of the machine, there is an EXP machine where you add experience items. On the right side, you will find the lever that starts the whole fusion process.
How to Use the Mutation Machine in Plants vs Brainrots
The mutation machine is basically a way to upgrade your mutated plants and brainrots. When you find the same plant or brainrot with different mutations, you can throw them into this machine and merge them together. The result? A stronger version with combined mutations and some bonus rewards on the side.
Using the machine might sound hard, but the truth is, it is actually super simple. Here is exactly what you need to do to merge your mutations successfully:
- Walk up to the machine while holding the mutated plant or brainrot you want to merge.
- Press E to place it into one of the two pods. Then, place another plant or brainrot of the same type in the second pod.
- Go to the EXP machine on the left and add EXP items until the total reaches 300 EXP.
- Move to the right side of the machine and pull the lever to start fusion. Wait for the timer to finish.
