Michigan J. Frog is an animated cartoon character who debuted in the Looney Tunes cartoon One Froggy Evening (December 31, 1955), written by Michael Maltese and directed by Chuck Jones. In this cartoon, Michigan is a male frog who wears a top hat, carries a cane, sings pop music, ragtime, Tin Pan Alley hits, and other songs from the late 19th and early 20th century while dancing and performing acrobatics in the style of early 20th century vaudeville. He appeared in a later cartoon titled Another Froggy Evening which was released on October 6, 1995. He was also a former mascot of The WB Television Network from that year until 2005, and after The Night of Favorites and Farewells, he was shown as the final image of a ghost bowing down to viewers, bringing up The CW Television Network.
In Night of the Living Buttons, he makes a cameo.
