A barrel from the world above falls into the ocean, letting out a reddish fluid that makes people frightningly zany. Meanwhile, the Snorks are performing in a talent show and Dimmy really sets a bomb with his jokes. Then the red stuff seeps in and makes everyone laugh. Of course, it gets out of hand when the entire town starts laughing crazily. The Snorks go out in the Silverfish to find the the problem at the Great Reef. The barrel is about to fall in the reef, but the Snorks get it out in time. But Junior and Occy, under the spell of the red stuff, take over the Silverfish! Eventually, Occy gets back to normal and so does Junior.
