"Magoo's Puddle Jumper" is a 1956 cartoon from UPA, directed by Pete Burness.
It stars, 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.
- The Alleged Car: Averted, since the old electric jalopy that Magoo buys runs underwater.
- Aluminum Christmas Trees: Why yes, electric cars were fairly popular in the early 20th century. They were slower than internal combustion engines and had short range, but the fact that they were so quiet, and the lack of a need for a hand crank to start them, led to a certain popularity for urban drivers.
- 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.
- 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."
