Moo Moo is a main character in the video game Air Zonk and a cross between a cow and a puffer fish which has no legs but only udders.

Zonk will turn into a cow from the waist down and shoot bottles of milk. They fire completely straight and the canisters deal splash damage. When the canisters are "splashing", it is possible to hit multiple targets, although unlikely. The attack, due to the canisters' persistence upon impact, deal heavy damage.
