In "Operation: T.R.I.C.K.Y. (Trivial Rival Instigates Candy Krazy Yearning)", it's trick-or-treat night, and Numbuh 4 sets off on his own to prove he can get more candy than his teammates - without even wearing a costume. But he only receives a single piece of butterscotch, and that ends up being stolen by Stickybeard and his candy pirates, who are taking trick-or-treat candy from neighborhood kids. Furious, Numbuh 4 races after them to retrieve his candy. At this rate, how will his candy count ever top that of his friends? In "Operation: U.N.C.O.O.L. (Undead's Nocturnal Craving Overtakes Operative's Love)", another Kids Next Door sector is being menaced by zombie nerds and calls upon the members of Sector V for help. Numbuh 2 is especially concerned for the safety of Numbuh 73. When the reason is revealed, it's not at all what any of his teammates expected.
