According to Tarung, this planet is filled with active volcanos and rivers of molten lava, which indicates that this planet is highly dangerous.
There is a Power Sphere hidden on the peak of a volcano, which is named FireBot as revealed in Episode 12. It is guarded by Sai and Shielda. Due to the immense attack of BoBoiBoy Fire, the volcano becomes highly unstable and will erupt soon. With that, Tarung stops the Toughness Test and gets everyone to TAPOPS Space Station. Yaya, Ying, and Gopal manage to retrieve the Power Sphere, hence, accomplish the test.
