Mighty Mouse was cancelled amidst controversy for allegedly depicting the main character snorting cocaine. Bakshi maintained that neither he nor Kricfalusi had the character sniffing cocaine, and that the character was sniffing the crushed petals of a flower, which were handed to him in a previous scene in the cartoon. In 1994, Kricfalusi pitched a revival series of Mighty Mouse to Paramount, which would have featured other Terrytoons characters such as Deputy Dawg, but they rejected the idea.
After leaving The Ren & Stimpy Show, Kricfalusi consulted, and other Spümcø animators worked for Donovan Cook's 2 Stupid Dogs, which was put into production by Hanna-Barbera president Fred Seibert. The cartoon's credits read "Tidbits of Poor Taste Supplied by John Kricfalusi" for the three "Little Red Riding Hood" episodes: "Red!", "The Return of Red" and "Red Strikes Back". In 1994, Hanna-Barbera and Seibert started production on What a Cartoon!, also known as World Premiere Toons for Cartoon Network. Siebert approached Kricfalusi for advice and for recommendations for personnel to head the shorts, among them David Feiss, Tom Minton, and Eddie Fitzgerald.
