In Plants vs Brainrots, merging different mutated plants or brainrots is a fun and smart way to earn more money and deal stronger damage. When you use the mutation machine, you also get free rewards. These rewards include rare plants, brainrots, and gears that help you grow faster in the game.
To get these rewards, you need to merge two plants or brainrots that already have mutations. Once you combine them, the machine gives you a random reward. There are twenty five rewards in total that you can unlock by merging again and again. The more you merge, the better the reward.
Some rewards include money, water buckets, card packs, potions, sunflower seeds, and rare characters like Gangster Footera and Bandito Bobrito. You can even get frost grenades and other special items as you go.
The mutation machine is found on the center island. You can reach it by using the mirror at your base. Once you are there, hold the two plants or brainrots you want to merge. Press the E key to place them inside the machine. Then walk to the left side where the EXP machine is placed. Use any EXP item like a potion or vial to start the merging process.
The time it takes depends on how rare your plants or brainrots are. But there is also a weather event in the game called mutation mania. During this event, the merging speed becomes double for ten minutes every hour. It is the best time to use the machine and collect more rewards quickly.
When you merge two plants with different types of mutations, you get a brand new version. For example, if you combine a frozen plant with a neon plant, you get a frozenneon version. It looks different and performs better in battles.
In short, the mutation machine helps you get stronger, earn more money, and unlock exclusive rewards. Keep merging your plants and brainrots to discover all the hidden rewards and special versions available in the game.
