The Chocolate Chase is a 1980 Looney Tunes short directed by Friz Freleng. This cartoon is part of Daffy Duck's Easter Egg-Citement, Daffy's award-winning Easter cartoon special, later it was shown on TV as a standalone short.
Daffy Duck is given the job of guarding the Chocolate Bunny factory from mice. The mice try to offer Daffy money, but he still refuses. The mice then decide to call Speedy Gonzales, the fastest mouse in all of Mexico. Speedy succeeds in every way he tries to bring chocolate bunnies to the mice, hurting and winning against Daffy Duck. Daffy chases Speedy Gonzales into the Chocolate Bunny factory, then gets stuck inside a giant chocolate bunny and all the mice laugh at him. Daffy, though, is eventually appreciative.
