Caustic Dirigibug

The Caustic Dirigibug is an odd creature. It is completely made out of water, has red eyes, and drops water bombs. When touched, the water bomb will explode and drench the surrounding area, causing all but Blue Pikmin to drown. Only Blue Pikmin could attack it.

How to Kill
Only Blue Pikmin can attack this beast. Even when it is defenseless, all other Pikmin will drown.

Trivia

 * The Caustic Dirigibug's water trait is similar to that of the Goolix because only Blue Pikmin can attack them.
