Fido Dido (pronounced: /ˈfaɪdoʊ ˈdaɪdoʊ/) is a cartoon character created by Joanna Ferrone and Sue Rose. Rose first developed the character in 1985 on a napkin in a restaurant. Fido Dido was licensed to PepsiCo in around 1988, but the character did not receive much attention or popularity until the early 1990s on numerous products, particularly stationery. Later, he was replaced with Cool Spot as the brand mascot. Fido Dido and other friends also appeared in Saturday morning bumpers for CBS from 1990 to 1993. In 1993, a Fido Dido video game was created for the Sega Mega Drive, but was not very successful.
