|Porky's Movie Mystery|
Mr. Motto returns from his vacation to try and catch an evil phantom.
The cartoon begins with a radio news report from Walter Windshield (a spoof of Walter Winchell). He reports that a mysterious phantom has been haunting Hollywood for weeks; ruining pictures and frightening stars. We then arrive at Warmer Bros Studios (a spoof of Warner Bros, the company that owns the Looney Tunes) where the phantom is on his rampage.
Studio cops went all around the lot, looking for the phantom. They even question famous movie monsters like Frankenstein, who's biting his fingernails as a cop was torturing him with questions.
Later, the phantom went up a twisty staircase all the way to the top and briefly sliding down a pole. Then he sneaks into The Invisible Man's dressing room and reveals himself to be The Invisible Man himself. He then tells his audience that the reason he's been doing what he's doing is because he was fired after starring in one picture (presumably his self-titled picture based on the book). Then he tells his audience that he will crack every camera, wreck every reel, smash every set and scaring off every star away from Hollywood, and laughs.
Fed up with the phantom's wrath, the public and the police call upon Mr. Motto (Porky Pig) to stop him. Unfortunately, Mr. Motto is currently on vacation. The police chief doesn't care if Mr. Motto is on vacation and demands that they summon him.
We later find Mr. Motto on a small island reading a book on Ju Jitsu. He suddenly receives a phone call and answers the coconut. The caller tells Mr. Motto about the phantom and so he ends his vacation flies off to Hollywood. He crash lands in the chief's office and greets the chief with a throw down. Mr. Motto apologizes and goes to work at once.
While Mr. Motto searched for the phantom, The Invisible Man phantom spots him, takes off his black attire and blends into a poster showing an actress named Lotta Dimples in a film called Great Guns. Mr. Motto came by, continues his search, and gets kicked by The Invisible Man. The Invisible Man then grabs an ax and attempts to kill Mr. Motto. The Invisible Man corners Mr. Motto at a wall but before he could finish him off, Mr. Motto read his book again, grabs the ax and attacks the phantom. Mr. Motto even puts the ax down. Mr. Motto punches the phantom, throws him around and finishes him off. Then as the reporter reports on what's about to happen, Mr. Motto grabs his anti-invisible juice and sprays it all over the phantom. The Invisible Man phantom is revealed to be Hugh Herbert?!
