How To Use the Mutation Machine
The new Mutation Machine is available on the Center Island. Just enter the Glass door in your plot to access the Center Island and make your way to the Mutation Machine. The Mutation Machine only accepts mutated Plants or Brainrots. You cannot add two Plants or Brainrots with the same mutation. For example, you cannot add two Gold Madungs to the machine. You will have to add one other mutation, like the Diamond mutation or the Rainbow mutation, to make the machine work.
Once you have added two Brainrots or Plants, you will have to add some EXP bottles to the machine. You can make some EXP bottles by adding Plants to the Plant Extractor machine. You will require five Plants to make EXP Bottles. Based on the rarity of your Plants, you will get Small, Medium, or Big EXP bottles. Once everything is added, you will have to wait for a while for the merging to complete. After some time, you will receive the merged items in your inventory!
