Gorgon

A Gorgon is a relative to Enigmas in Super Mario RPG: Legend of the Seven Stars. They are encountered in the Sunken Ship. Although a Gorgon resembles a large, green bat, the monster is actually a colony of smaller bats that come together to create one larger Gorgon. Somehow, these bats can both think independently and combine their consciousnesses to act as one being. Interestingly, the large Gorgon resembles the small bats that make the monster up; however, Gorgons are a lot lumpier than their smaller counterparts. This is because a Gorgon is not made up of one bat, but many bats. These bats can even detach themselves from the group and reform into different shapes.

Trivia

 * It is possible that Gorgons are named after the snake-haired, female beasts of the same name who originated from Greek mythology.
