Shockuta

This type of Mamuta is anything but calm. It will go after your Pikmin in a psychotic rage. Instead of replanting Pikmin, this beast will electrocute Pikmin. It creates a ball of blue electric energy. It will then toss it towards your Pikmin and when it hits the ground or any other object it will spread. Every Pikmin besides Yellows with instantly die.

How to Kill
The only way to damage this beast is to use Yellows. Captains can also kill this beast when they obtain a certain item.
