Magoo's Puddle Jumper is a 1956 animated short from UPA, directed by Pete Burness and starring, yep, Mr. Magoo.
Magoo, voiced as usual by Jim Backus, goes to buy a car. The sleazy used car dealer sells him an electric car, against the advice of his nephew Waldo. Magoo, who naturally insists on driving, then goes on a death-defying ride through town that eventually has him and Waldo driving the car into the ocean.
Tropes:
- The Alleged Car: Averted, since the old electric jalopy that Magoo buys runs underwater.
- Amphibious Automobile: Mr. Magoo buys an electric car and takes it out on a spin with his nephew Waldo. Due to being near sighted, Mr. Magoo drives his new car into the ocean and thinks he's in a different part of town.
- Blind Driving: Before driving into the ocean, Magoo drives through a bar.
- Celebrity Paradox: Magoo thinks all the shipwrecks and litter at the bottom of the ocean are urban decay in Beverly Hills, saying "Look how they let the old Backus mansion run down."
- Honest John's Dealership: When Waldo expresses some skepticism about buying an ancient electric car, the used car salesman yanks his hat over his head, leaving him incapacitated while Magoo signs the papers.
- Idiot Ball: At least Magoo has the excuse of being legally blind. Apparently Waldo doesn't realize they're underwater because he's a moron.
- Late to the Realization: Very late. It isn't until Magoo opens the driver's-side door and the car fills up with water that Waldo realizes they're underwater.
- Verbal Irony: Magoo mistakes a whale for a blimp, and says he'd never ride in one, saying "I want my feet on dry land."
