Aristotle

Aristotle is a blind monster who appeared on Sesame Street during seasons 13 and 14, first seen in Episode 1577. He was friends with Telly, and was sometimes called Ari for short. His name is borrowed from the Greek philosopher. Aristotle loves to help others and is an avid collector of things of all kinds. Among other things, he's mentioned having collections of broken sports gear, lettuce, music and things beginning with the letter F. Aristotle is one of the few monsters to be built with visible ears. Other monsters with ears include the monster group the Shagri-Las.
