How to Unlock New Biomes in Plants vs Brainrots
You can unlock new biome totems in Plants vs Brainrots by progressing through the Story Brainrot Invasion events. The base biome every player has unlocked from the start is the Grasslands. Desert and Jungle biomes are unlocked after completing the 25th and 50th Story events, respectively.
How to Complete Story Brainrot Invasion Events
Story Brainrot Invasion events appear around 15 minutes after completing the previous Story mission. Once triggered, there is an additional 15-minute preparation window before you can activate the Story battle. The Story battle itself lasts only for around 2 minutes, and you have to defeat all brainrots that spawn to complete it.
As you progress through the Story missions, brainrots in them will spawn with more and more HP, which can be too much for your plants to handle. However, you will be able to activate the same battle again after the usual cooldown period. Here are some things that can help you beat Story missions more reliably:
- Frost Grenades, Handcuffs, and Frost Blowers: These allow you to slow down and stun brainrots.
- Plant DPS and impairment cards: Cards such as Doom Bloom and Bloom Ascendant can significantly boost the DPS of your plants, while Whirlwind and Overgrowth help slow down brainrots even further.
- Potions: Damage and Speed potions boost the damage and attack speed of your plants for 30 minutes. You can obtain potions from Admin Abuse and other events.
How to Switch Biomes in Plants vs Brainrots
After you unlock the Desert biome, a small totem will appear next to the bridge on the left side of your island, which allows you to change the biome on your island. In the same menu that opens up, you can see which Secret units are exclusive to a specific biome. So, if you need a Secret brainrot such as Meowzini Sushini for a fuse recipe, you will have to switch to the Grasslands biome to get it. Similarly, to obtain Meowtronzio and Rexosaurus for Rebirths 8 and 9, you need to activate the Desert biome.
