Crump's Playworld is in trouble. The Ferris wheel won't spin. The coin-stamping machine won't stamp coins. The grille won't serve food. After seventy-five years, Crump's is falling apart. The amusement park needs help fast, or it will have to close. Max, Jessica, Quincy, & Selena offer to lend a hand -- but then things at Crump's start getting even worse. Much worse. Is someone trying to put the amusement park out of business? Will the Abracadabra Club be able to stop them?
