Hydro Mamuta

This type of Mamuta is always running around the area. It is blue with light blue hands and purple eyes. It will run towards your Pikmin in a clumsy manner though. It may occasionally trip. Instead of replanting Pikmin, this beast will drown Pikmin. It's hands now have holes in them and they look similar to the Pokemon Magmortar. It will charge up water in its organs ad release in a powerful jet of water. Every Pikmin besides blues will drown. It is also surrounded by an invisible shield that will drown all Pikmin except blues.

How to Kill
The only way to damage this beast is to use blues.
