Don's Fountain of Youth

Don's Fountain of Youth (1953) is a Disney animated short you can watch online on iFILM, directed by Jack Hannah with Clarence Nash voicing Donald Duck.

Donald and his nephews stumble onto what might be the legendary Fountain of Youth, and Donald cannot resist staging a prank — he acts like a baby, convinced he has reverted to infancy. The nephews fall for every second of it. Then a mother alligator shows up with her brood and Donald's triumphant performance gets a very rude interruption. Six minutes of peak Burbank-era Disney mayhem. Stream it on iFILM.
