Magical Maestro is a 1952 American animated short comedy film directed by Tex Avery and produced by Fred Quimby for MGM Cartoons.

In 1993, Magical Maestro was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant", making it the only Tex Avery cartoon so far to be inducted.

Poochini is then transformed into a Shirley Temple-esque child (who sings "A-Tisket, A-Tasket" before the balloon blows up and pops), then a Carmen Miranda-type singer, singing "Mamãe Eu Quero" (with two rabbits accompanying him on guitar) after an irritated audience member hurls an armload of fruit onto Poochini's head where it piles up like Miranda's headdress.

Now set for revenge of his own, Poochini furiously grabs the hairpiece and puts it on while a now defeated and exposed Mysto cowardly tries to flee; but Poochini, having also grabbed the magic wand, stops the magician by using the wand on him as placing Mysto to the stage and unleashes the same gimmicks on the hapless magician at high speed.

Because cartoons were shown originally in movie theatres, the film strip, if loaded incorrectly, would rub against the gate mechanism, shaving off tiny "hairs" of celluloid.

In this cartoon, the opera singer pauses mid-song to pluck the offending hair from the film and tosses it aside,[5] one of Avery's many ways of his characters breaking the fourth wall.

The role of Poochini is portrayed by Butch the Irish dog, a frequent star of Avery's cartoons of that era (often alongside Droopy).
