Cover: Marco morphs into a Squirrel.
Taglines: Let's Get this Party Started; Pillow Fight, anyone?
Plot: Marco gets word of a slumber party Rachel, Cassie, and Melissa Chapman are having at Rachel's house. Marco convinces the male Animorphs, and Ax, to spy on the party to see what's going down. But Visser Three is upset that he didn't get an invitation, so he decides to throw a sleep over of his own, but so much cooler, across the street with Chapman and Tom. Visser Three plans to sabotage Rachel's slumber-party, and making her look lame in front of all the kids at school! Hilarity ensues.
