Hare Ribbin'

"Hare Ribbin'" is a 1944 animated short film that follows Bugs Bunny as he evades a Russian Poodle voiced by Sam Wolfe (uncredited) and Dog (Elmer Fudd voice). The chase takes an underwater turn as the dog transforms into a torpedo to pursue "her" while Bugs disguises himself as a mermaid. In the end, Bugs outwits the dog with a comical twist, leading to multiple endings including one where the dog is initially fooled into thinking he's dead and later reveals he's still alive, commenting on his misfortune.
