A plumpkin is a type of animal which is rarely found on Earth. The requirements for a creature to qualify as a plumpkin are that it must be a carnivore, and its mouth must at least appear to make up at least 40% of its entire body. Plumpkins are also often round, and usually are willing to try and eat just about anything. This makes for a creature which is essentially just a head. It is also not uncommon for plumpkins to have small, mostly useless arms.

Most plumpkins are found in fiction, but there are some real-life examples, such as the deep sea anglerfish.

Example in Game: The Cacodemons in "Doom" (1993)

I hooked-up with a plumpkin at the mall food court, hoping to gradually sweat the jellyrolls off of her. But once she had a man, rather than getting leaner and hotter, she just got lazier and bought bigger clothes.
