Acidic Dirigibug

Acidic Dirigibugs are a species of Dirigibug that uses highly acidic energy balls to attack with instead of bombs. It is green, like the Careening Dirigibug, but it has purple eyes and blue balloons. When dropped, an acid ball will explode, causing smaller energy balls to scatter and instantly killing Pikmin except for Green Pikmin.

How to Kill
The only way to kill this beast is by throwing Green Pikmin, as no other type will work.
