Anode Dirigibug

In Pikmin: The After Years
The Anode Dirigibug is a dirigibug that regurgitates high-voltage energy balls to attack using instead of bomb rocks. The body of the creature is brown, its eyes are green, and it has yellow flotation sacs, of which are electrified. The energy balls it spits out will detonate upon impact with a surface, creating a short-lasting but powerful surge of electricity on the ground where it landed. Because of the Anode Dirigibug's reliance on electricity, only Yellow Pikmin can be used to battle it.

In Pikoblitz: Raging Winds
In Pikoblitz: Raging Winds, their bodies are not electrified and they drop static bomb rocks.
