Cam's sister is in trouble. Again. Her parents are not happy. Not even a little. And who can blame them? Pam really messed up this time. Sure, she has done some rotten, nasty things before. Like trying to help the monsters take over Blurg Burg. Or hiding when Cam needed her help. Or being an all-around mean person. But this time she's gone too far!!! There's only one thing left to do. Pam is forced to be Cam's sidekick for a day so she can learn how to do something good for once. The trouble is, Cam and Pam might knock each other's heads off first!
