Bloodthirsty shrimp

The bloodthirsty shrimp is a giant sea monster living on the planet Earth in the year 351120, whose body is attached to what looks like a Merfolk, presumably for use as a lure. It has two red eyes, eight brown arms and claws, and crustacean skin. The creature ate Professor Farnsworth, Fry, and Bender when they made a stop in its time during their forward time travel. It is remembered in the song In the Year 252525.
