Joanna Ferrone, Sue Rose
Fido Dido /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. They later stenciled Fido on T-shirts with the credo: "Fido is for Fido, Fido is against no one". These T-shirts became very popular in New York.
Fido Dido was licensed to PepsiCo in 1987, but the character did not receive much attention or popularity until the early 1990s, when he appeared on numerous products, particularly stationery. Later, he was replaced with Cool Spot as the brand mascot.
