The Jungle Biome in Plants vs Brainrots is one of the most exciting areas introduced in the Story Update.
It’s filled with lush greenery, tougher enemies, and brand-new Secret Brainrots that can’t be found anywhere else.
But before you can explore this mysterious new region, you’ll need to prove your strength through multiple battles in Story Mode.
This guide explains exactly how to unlock the Jungle Biome, what challenges you’ll face on the way, and all the Secret Brainrots that await you inside.
How To Unlock the Jungle Biome in Plants vs Brainrots (Full Guide)
Step 1: Unlock the Desert Biome First
Before you can access the Jungle Biome, you must first unlock the Desert Biome, the first major unlockable area in Story Mode.
The Desert Biome becomes available after you complete Orcalero Orcala’s storyline (Invasion 25).
Once unlocked, it introduces a whole new set of challenges, enemies, and exclusive “Secret II-tier Brainrots” like Pepito Di Pollo II and Rexosaurus Hatcherini II.
The Desert acts as your proving ground before the Jungle. You’ll need to complete all of its missions and prepare your plants with higher damage, resilience, and upgraded mutations to survive the tougher battles ahead.
Step 2: Complete All 50 Story Mode Missions
To unlock the Jungle Biome, you must reach and defeat the final boss in Story Mode — The Elephant Guide and Moss King — during Invasion 50.
This marks the end of the tenth storyline in the Story Mode progression. The battle against the Moss King is a true test of endurance and coordination, requiring the right plant combinations and gear setups.
Tips for the Final Story Missions:
-
Upgrade your plants to their highest levels possible before starting the 46–50 invasion streak.
-
Use strong support plants like Carrot Launcher and Frost Blower to handle large Brainrot waves.
-
Stock up on potions — particularly Damage Potions and EXP Bottles — as these final fights feature some of the hardest Brainrots in the game.
-
Avoid early aggression. Instead, place defensive plants near the end of your garden to slow the Brainrots’ approach and prevent an instant fail.
Once you successfully defeat the Moss King, the Jungle Biome will unlock automatically.
What Happens After Unlocking the Jungle Biome
After unlocking the Jungle Biome, you’ll immediately gain access to a new world with tougher terrain, exclusive loot, and new plant combinations. The Brainrots here are Tier 3 Enemies, much stronger than anything you’ve encountered before.
This biome also introduces five exclusive Secret Brainrots — creatures that can only be found here and nowhere else in the game.
