The Magilla Gorilla Show (1964)

S1E9 Hornswoggled

During their ongoing rivalry, Mushmouse discovers a dog trapped with its muzzle stuck. After freeing the dog, it promises to lend a paw if Mushmouse ever finds himself in trouble. Meanwhile, Punkin’ Puss is determined to catch Mushmouse before he can reach out to his newfound ally. When “Stinky” steps in to assist Punkin’ Puss, their plan backfires spectacularly when a moose misinterprets the sound of Punkin’ Puss’ horn as a mating call. Chaos ensues as the four of them are chased through the hills by an infatuated moose.
