Everbody knows that ice cream comes in three basic flavors - chocolate, vanilla, and strawberry. But Numbuh 5 knows only too well the legend of how the ancient ice cream monks created a FOURTH basic flavor, and hid it away in a hidden temple, where only an ice cream lover with the purest taste buds could ever taste it. But when the Delightful Children steal the sacred Golden Scoop, Numbuh 5 finds herself dragged to the trap-laden temple, where the evil children force her to penetrate its inner sanctum. Will Numbuh 5 prevail in this frozen frenzy and get a taste of the fabled Fourth Flavor?!
