Corrosive Droneule

Corrosive Droneules first appear in Pikmin: Corporate Combat. This creature is identical to the Impaling Droneule, except it has a green-tinted shell and red bulb. It is otherwise the same except for when it loses half its health, as it will spray acid from its underside. Said acid kills all but Green Pikmin.

How to Kill
Rock Pikmin cannot be impaled by this creature. Once it reaches half health, however, either switch out your Rock Pikmin for Green Pikmin. For the more daring type, keep the Rock Pikmin with you and avoid the acid attacks.
