When Bugs Bunny kisses the Tazmanian Devil with the steel trap in his mouth, the trap ends up on the Tazmanian Devils mouth but it ends up on his mouth backwards.
When Bugs reads, in alphabetical order, the things that Tasmanian Devils eat, one of then is "people" However "people' is not what appears in the book. Insteed "Widgeons" is what's on the page.
When the Tasmanian Devil first appears and drops out of his unique 'tornado' motion, the gibberish sounds of his speech begin before his mouth starts to move and remain out of sync with the animation until the end of the scene.
