How to Use the Mutation Combiner in My Fishing Brainrot

The Mutation Combiner is a handy machine in My Fishing Brainrot that you can use to free up brainrot slots. You can place two brainrots in the Mutation Combiner and get both their mutations on a single brainrot.
For example, say you have two Tung Tung Sahurs. One has the Frozen mutation, and the other has the Galaxy mutation. You can put both these fishing brainrots in the Mutations Combiner to fuse them into one brainrot that will have both the Frozen and the Galaxy mutation.
To use the Mutation Combiner, follow these steps:
- Pick up two brainrots from your plot that you want to combine.
- Head to the Mutation Combiner machine located next to the Wheel Spin.
- Place the brainrots in the two slots one by one and hit the Combine button in the middle.
- Wait for the timer to hit zero and claim your combined brainrot.
While using the Mutations Combiner, keep the following things in mind:
- You can only combine the same brainrots and their mutations.
- The resulting brainrot should not get more than 3 mutations, or the process will fail.
- You can not combine different Variants. Only the same variants can be combined. (Gold x Gold OR Diamond x Diamond).
