Mr. Bogus (partially lost animated TV series; 1991-1993)
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.
Premise
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.
Loss
This animated series didn't have a proper re-release after it finished being re-aired on TV in English. It had a few VHS releases in miscellaneous foreign countries, but most episodes that are available online come from personal recordings.
Many episodes have been recovered, but are only available in a foreign dub ranging from Portuguese, Greek, French, Croatian and Korean.
