Plants vs Brainrots gives you more than just tower defense action. The game throws different weather events at you that can help you get special mutations for your plants and brainrots. Some happen randomly while you play, and others need admins to trigger them. Let’s break down everything you need to know about Plants vs Brainrots weather events!
What Weather Does in Plants vs Brainrots
When a weather event starts in Plants vs Brainrots, it affects your whole server. Your plants might deal more damage, or you might see rare brainrots spawning more often. The main thing weather does is increase your chances of getting mutations. Mutations make your plants and brainrots look different and give them special powers or boost their income.
You can tell when the weather event is active because the game world changes. The sky might get foggy, the grass turns different colors, or special effects appear around the tunnel. Each weather type has its own look and benefits. The events are also divided into two categories: Standard and Admin.
