Prickle's only played the clarinet for one day, but that's no reason why he can't perform with the band at the cherry festival. By a stroke of luck, he happens upon the pitch that shatters every glass object in the city, and he, along with Gumby and other friends, run away before he can be prosecuted. They all duck into the book called "The Glass Menagerie and Dr. Jekyll". They find a glass museum, run by a mad scientist old movie Dracula, who lets them visit for free. Unfortunately, that's only because he plans on turning them into glass sculptures. He traps everyone under giant wine glasses, except Prickle, who finds his clarinet and shatters the glass again, freeing them. The moral: clarinets have as much potential for good as they do for evil, and must not fall into the wrong hands.
