Boo! Jessica's little brother Noah is terrified of ghosts. He has started hearing funny ghost noises all over the school - in the bathroom, in the halls, even in the stinky janitor's closet. At first, everyone thinks he's just trying to get attention (Noah loves attention...for anything, no matter how big or small). But soon Quincy, Max, Selena, and even Jessica start to hear ghosts,too.The Abracadabra Club's first big magic show is coming up. But it looks like it might be cancelled because of a chatty ghost. They have to stop the spooky sounds before their performance is ROOOOined!
