Michigan J. Frog is a one-hit wonder of the Warner Brothers cartoon stable, star of the 1955 Warner cartoon One Froggy Evening (directed by Chuck Jones). Michigan is a singing, dancing, tophat-wearing frog who confounds a construction worker who discovers the amphibian in a time capsule. (The cartoon was loosely based on Old Rip, a toad found in a time capsule in 1928). In the 1990s the WB television network brought Michigan J. Frog back as the network's official mascot.
