Bugs and Porky are running a messenger service. The Maharajah of Wishawasha, one of the richest men in the world, sends the pair to Wishawasha to retrieve a "Bad Luck Charm" of an ivory elephant that he uses to counteract his fabulous good luck. Thieves steal the charm and Bugs and Porky have to trail them into the desert.
Porky and Petunia find that her great-grandfather's overalls and her great-grandmother's bonnet are made of an indestructible fabric that protects the wearer from harm. Two crooks steal the clothes and use them to rob a bank. Petunia finds that the indestructible fabric comes a plant on a remote island. When she and Porky go there, the crooks stowaway on their ship.
