Plants vs Brainrots Mutation Machine Guide – How It Works and All Rewards

One of the most exciting mechanics in Plants vs Brainrots is the mutation merging system, where players can combine different mutated plants or brainrots to create stronger versions. This feature not only helps increase your earnings and damage output but also gives you special in-game rewards for each successful merge. Here’s everything you need to know about how the Mutation Machine works and all the rewards you can get from it.

How the Mutation Machine Works

The Mutation Machine in Plants vs Brainrots functions much like the fusion machine, but with added benefits and exclusive bonuses. You can find it on the central island, accessible through the mirror portal at your base.

Once there, hold the two mutated brainrots or plants you want to merge and approach the machine. Press E to place them inside and begin the merging process. Keep in mind:

• You can only merge the same type of plants or brainrots, but they must have different mutations.
• For example, merging a Frozen plant with a Neon plant creates a FrozenNeon hybrid.

After placing your items in the machine, head to the EXP station located on the left side. Use any EXP item—such as vials or potions—to power up the machine and start the mutation.

The mutation process time varies based on the rarity of the items used. However, it becomes much faster during the Mutation Mania event, which occurs every hour and lasts for 10 minutes, granting 2x mutation speed.

All Mutation Machine Rewards

Every time you complete a mutation merge, you’ll receive unique rewards. These rewards include powerful plants, rare brainrots, valuable gear, and currency bonuses. Here’s a complete list of currently known rewards from the Mutation Machine:

• Mutation Merge #1 Money
• Mutation Merge #2 Money + Premium Water Bucket
• Mutation Merge #3 Frost Grenade + Orcalelo Orcala
• Mutation Merge #4 Money

Tips for Using the Mutation Machine

• Always merge plants or brainrots of the same type but different mutations to ensure a successful fusion.
• Save your EXP potions for when you plan multiple merges at once—it saves time and boosts efficiency.
• Take advantage of Mutation Mania to double your progress speed and get more merges done in less time.

The Mutation Machine in Plants vs Brainrots is a key feature for both progression and profit. By experimenting with different mutation combinations, you can unlock new versions of your favorite plants or brainrots and claim exclusive rewards. As more merges become available, the reward list will expand—so keep experimenting and tracking your progress. Which mutation are you most excited to try next?
