Aquatic Beast

The aquatic beast is a boss that is actually also an easter egg. This beast is actually a Magikarp from the Pokemon series. It is found in areas where the water is very, very deep.

How to defeat it
First you need to gather at least 50 Blue Pikmin. Then from there on keep dodging its water jets, and then throw pikmin on its eyes. When it knocks them off, just repeat the process until the beast dies.
