Rabbit, Duck!", "Bully for Bugs", "Knighty Knight Bugs", "Hare-Abian Nights", "Spaced Out Bunny", "Mad as a Mars Hare", and "Hare-Way to the Stars", while the other level, entitled "Haunted Hare", is based on elements of "Bewitched Bunny" and "Hair-Raising Hare". On the Game Gear version, the "Bully for Bugs" level is altered to instead be named and based on the cartoon "Roman Legion-Hare", though similar gameplay is maintained.

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!"
