The difference between a fused and a mutated Brainrot is that fusing combines 4 different Brainrots into one rarer Brainrot, while mutating combines 2 of the exact same Brainrot into a single mutated version.

You need a stronger Pickaxe because higher-rarity Lucky Blocks have more HP and take longer to break with a weak Pickaxe, slowing down how fast you can reach rarer Brainrots.

The Brainrot Trader's stock changes every 30 minutes, offering 4 rotating Brainrots at a time, so getting a specific one through trading means waiting for the right rotation.

Yes, you keep the Brainrots, Pickaxes, and Gear included with my purchase, exactly as shown in the listing.
