Hank is an old shrimp who has a human mind. He served in the army to fight people who eat seafood and held the rank of junior lieutenant. He still has a tank, shaped very much like a fugu fish. He lives with Otis (an octopus), who is like a grandson to him, but he still gets really pissed off every time Otis paints the walls. Rude, cold, with military training, but honorable.
