Mutations are a core part of the game's progression system. They change the appearance and stats of both plants and brainrots, with mutated plants dealing significantly more damage and mutated brainrots generating more cash per second. Mutations are applied randomly to your units, and each one comes with a different multiplier that can drastically boost your gameplay.

Plants vs Brainrots Mutations Guide
Plants vs Brainrots includes nine mutations that enhance either plant damage or brainrot income generation through stat multipliers. These mutations fall into two categories: RNG-based and weather-triggered. RNG-based mutations can appear at any time when planting seeds or collecting brainrots, while weather-triggered mutations only appear during their specific weather events.
The Galactic mutation offers the highest multiplier in the game at 8x, but it comes with a very low drop rate of just 0.05% during Galactic weather. On the other end, the Frozen plant mutation has the highest drop rate among weather mutations at 15%. Frozen plants not only deal 4x damage but also stun brainrots for 0.3 seconds with each attack, making it one of the most useful mutations for defense.

Conclusion
Mutations are essential for progressing in Plants vs Brainrots. Focusing on weather events gives you the best chance at landing rare mutations, while RNG-based ones like Gold and Diamond will naturally appear over time. If you're looking to maximize your defense, prioritize Frozen plants for their stun effect, and for income, aim for Galactic brainrots during Galactic weather for that 8x multiplier.
