Development of Bugs Bunny slightly modified again for the 2011 series "The Looney Tunes Show" and yet again for the 2015 series "Wabbit". Development of Bugs Bunny A prototypical version of Bugs Bunny appeared in four cartoon shorts before making his first official appearance in Tex Avery's "A Wild Hare". While this prototype version is commonly referred to as "Happy Rabbit", animation historian David Gerstein disputes this, saying that the only usage of the term was from Mel Blanc himself; the name "Bugs Bunny" was used as early as August 1939, in the Motion Picture Herald, in a review for the short "Hare-um Scare-um".
Bugs Bunny in both the 855th Bomb Squadron of the 491st Bombardment Group (Heavy) and later in the 786th BS of the 466th BG(H), both being part of the 8th Air Force operating out of England. In 1944, Bugs Bunny made a cameo appearance in "Jasper Goes Hunting", a Puppetoons film produced by rival studio Paramount Pictures. In this cameo (animated by McKimson, with Blanc providing the usual voice), Bugs (after being threatened at gunpoint) pops out of a rabbit hole, saying his usual catchphrase; after hearing the orchestra play the wrong theme song, he realizes "Hey, I'm in the wrong picture!"
