This page of the Biomutant guide describes the Back to the Roots side quest. Here we've described everything you need to do in order to complete the quest and earn the rewards.
Starting the quest
How to start: Complete the main task - Another World.
Reward: 500 XP.
You will find Nono in the area of pink flowers in different parts of the map.
It's a simple task. All you have to do is enter a certain area, and you will see orange Nono, who will start running away from you. Grab it with the Web Rod.
With every Nono you acquire, you must go to the roots. With the magical power of Nono, you can strengthen and regenerate.
