Bladder beast

The Bladder Beast is a creature derived from the Methug Commander. It is basically a huge pus bag that “moves” by inflating parts of its body via hydrogen, which makes it move surprisingly fast. Its primary attack is to toss corrosive globs from the poisonous sacks on its neck. If someone gets next to it, it will fully inflate itself and start hitting the target with the poison from its skin.

It has two attacks, to toss a projectile and a melee attack. They usually come in groups.
