Aquamania

Aquamania is an American animated short film produced by Walt Disney Productions and released by Buena Vista Distribution on December 20, 1961. This cartoon was the last from Disney's "Golden Era" which featured Goofy as a solo star, and the first time the xerography animation-technique was used in a Goofy cartoon. Aquamania combined Goofy's three familiar areas in his career: sports, fatherhood, and documentary-subject.
