Star is sent to detention for disrupting Miss Skullnick's class when she frees the class's pet hamster Marisol. Although she could easily escape, she is convinced by Janna and the other detention students that she is the Mayor of Detention, and is assigned to help the students out with their needs. She helps all of them except for Toby, a kid who wants replacement batteries for his remote so he can watch a pro wrestling show on TV. Star and Janna try to find replacement batteries by sneaking out to Oskar and getting ones from his keytar. Meanwhile, Marco is tasked to find Marisol and gets his hand stuck in a drain pipe.
