Angry that Libby is having a Halloween party that pointedly excludes them, Valerie blurts out that she and Sabrina are hosting the coolest possible party at Sabrina's house. When a reluctant Sabrina backs up her friend, she discovers that her aunt's new furniture delivery includes talking chairs and couches infested with talking termites; and when Libby's bored guests crash her party, she conjures up 10,000 Maniacs to distract her schoolmates, who assume everything that happens is a "cool" Halloween special effect.
