Beanstalk Bunny

'Beanstalk Bunny' has the distinction of pulling together several standard Looney Tunes conventions, most of these distinct to director Chuck Jones:

The unique skewering of a classic fairy tale story already done by rote dozens of times by other studios.

Casting Daffy Duck in a stock starring role, his being aware of playing the part, and failing spectacularly.

Elmer as a potentially dangerous adversary who gets easily stalled and confused by Bugs' persuasive power of speech.

Jones' having Bugs content to mind his own business until external forces prod him to action.

Jones' oft-used staging a scene behind glass, where character acting makes dialog unnecessary.

Jones' tendency to put small characters in outsize surroundings, seen throughout his career, from the maudlin 'Tom Thumb in Trouble' to the bizarre 'I Was a Teenage Thumb'

All that, and a hilarious cartoon. How does Daffy come up with 'Aloysius'?
