Plants Vs Brainrots is a popular Roblox game where you have to grow Plants to destroy various other Brainrots. The game is not just about growing Plants and fighting Brainrots, but it also enhances your in-game experience with various new events and biomes. One such biome is the Mushroom Marsh biome.
The latest update introduced the Mushroom Marsh biome. Moreover, this biome also has its own Brainrots, which makes it even more interesting. However, unlocking this biome is not as easy as you think. So, to help you unlock it, here’s a complete guide on how to unlock Mushroom Marsh Biome in Plants Vs Brainrots.
How to Unlock Mushroom Marsh Biome in Plants Vs Brainrots

To gain access to the Mushroom Marsh biome, you must complete all 150 story missions in Plants vs Brainrots. But before you can even begin that grind, you need to complete 25 missions in the Winter biome. If you have yet to unlock the Winter biome, you will need to progress through every biome that comes before it.
So, to unlock the Winter biome, you need to defeat all the Brainrots across Grasslands, Desert, Jungle, Cherry Grove, and Birch Forest in sequence. Each story mission comes with a 30-minute cooldown, so even if you play continuously, unlocking Mushroom Marsh will require an ample amount of time.
However, story missions are far easier than they used to be, so the process no longer feels as punishing as it used to be. So, to speed up the process, you must level your plants up to at least level 10. Likewise, you can use EXP Potions from the shop or earn them through events like the Vaulted Event for a faster and smoother progression.
