Retro Goofy

Retro Goofy is a form when Goofy visits Timeless River with Sora and Donald, they are all converted into the older versions of earlier cartoons. In Goofy's case, he is largely based on the prototypical Goofy, then-Dippy Dawg, from the 1932 cartoon Mickey's Revue. Here, the future Goofy was portrayed as an annoying elderly member of the audience and a running gag of the short. Retro Goofy is primarily a younger version of said character. This younger version first appeared in Goofy's next cartoon, The Whoopee Party.

In this form, his legs and arms are slightly longer, and he wears only a retro jacket and a white hat.

He can fight with his shield like his usual appearance.
