Simply Simon Trollz : Season 1 Episode 15

The girls are on the run from Sheriff Snarf's ogre deputies when the come upon the perfect way to sneak into "King" Simon's castle: disguised as a traveling troupe of male actors (girls were not allowed). Just before Simon's massive clockwork magic-absorber can suck all of the magic out of Olde Worlde Trollzopolis, Sapphire's clever adjustments send the magic streaming back - and send Simon and Snarf flying out of town. Trollzopolis is changed back to its loud, bright, modern self.
