Jack-Wabbit and the Beanstalk is a 1943 Warner Bros. cartoon in the Merrie Melodies series, directed by Friz Freleng and starring Bugs Bunny,[2] with all of the voices provided by Mel Blanc.

[3][4] In a twist on Jack and the Beanstalk, Bugs Bunny finds himself in a giant's realm in the sky, where he angers the dim-witted giant by chopping down carrots in his victory garden.

Bugs spends the movie evading the giant, even challenging him to a duel.

In the end he tricks the giant into falling from the sky-land to earth, leaving a canyon-like hole in the ground from which he delivers the final line: "watch out for that first step, it's a lulu."

It should not be confused with Beanstalk Bunny (1955), another parody of this story starring Bugs Bunny, Daffy Duck, and Elmer Fudd.
