Punky Brewster - S04E10 - Radio Daze.

Punky’s favorite rock radio station went bankrupt and is now acquired by a firm that switched the format to dramatic performances. In order to encourage kids’ interest in older radio, the new owners sponsor a contest where whichever group gives the best performance will get a trip to Disneyland. Punky, Cherie and Marguax learn about old-time radio and how the actors made their own sound effects right in the studio, which looks like fun, but Punky’s zeal is tempered when she must take on Garth Goobler (Jason Hervey) and Grant Goobler (Ryan Rushton), the sons of a famous radio star. Henry encourages Punky to get to work on a script, telling her she can never become an astronaut or like profession if she only worries about competitors. The Gooblers have a strong script, and they steal a box of sound effect equipment from Punky and Cherie, but the girls quickly gather some more sound effect equipment and are able to pull off the win.
