Fido the Fly is a supporting character in The Upside Down Show.


Fido is Shane's imaginary pet and friend. He lives behind a minuscule door in the apartment.


Fido is never seen, as he is imaginary. However, it is likely that Shane and David imagine him as having the appearance of a common housefly.


Fido appears in every episode of The Upside Down Show, with the exception of Movie Theatre and Airport. He did not physically appear in Barbershop, but is mentioned by Shane.
