Mr. Bogus is an American animated TV series originally aired in September 1991 until November 1993. It had three seasons and had 43 episodes total.
The show was based on a series of over 300 French/Belgian claymation shorts called Bogus from 1987; about 42 were inserted in the 1991 American series proper as transitional skits.
Mr. Bogus is a tiny yellow gremlin-like creature who lives between the walls of a normal suburban house. He likes to play with common household objects and tends to get involved in trouble, but he is a good-natured person and tries to help others too, usually the humans of his environment who are unaware of his existence.
