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. At the end, Daffy chases Speedy Gonzales into the Chocolate Bunny factory. Daffy is stuck inside a giant chocolate bunny and all the mice laugh at him. Daffy, though, is shown to be appreciative at the end.
