Mutations boost a plant's damage or a Brainrot's passive income, with each tier giving a bigger multiplier, Gold and Diamond offer smaller boosts, while Neon, Rainbow, and Galactic sit at the top with the highest multipliers in the game.

Yes, a Frozen plant is worth it even compared to some higher-tier mutations, since it adds a freeze effect on top of its damage boost, giving real crowd control that a straight damage multiplier can't match.

No, not all mutations apply to both, some, like Rainbow and Galactic, are Brainrot-only, while others like Frozen, Gold, Diamond, and Neon apply to both plants and Brainrots.

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