Pissing Shrimps

Pissing Shrimps are the seaborne cousins of Piss Ants and a key ingredient in Exploding Pissing Beef Balls. They are the reason that the South Dragon Sea is nigh impassable due to its high acidity and disgusting smell.

Because of the impossibility of submerging scientists in oceans without them drowning, not much is known about pissing shrimps besides the fact that they piss A LOT. It is uncertain how they piss so much, but several scientists suggest it's because they live in bodies of water; therefore, the only thing they can do is regurgitate their water intake and piss it all out, before drinking it all in again.

If this is the case, there is no sadder creature in existence.
