Plot
Mad scientist Mickey has just brewed up a potion; to test it out, he squirts it on a fly that's been trapped by a spider, a (regular) mouse being harassed by a cat, then the cat when Pluto goes after it, and Pluto when dogcatcher Pegleg Pete goes after him. Each of the underdogs turns against his tormentor.
Sinekatalog’s take
Mad-scientist Mickey tests a potion that makes bullied creatures fight back, from a fly to Pluto. A brisk, inventive cartoon with a chain-reaction gag structure that holds up as classic animation.Sinekatalog’s own editorial review – not a user or critic quote.
