In "Operation: D.U.C.K.Y. (Dirty Unwashed Captain's Kowardly Yacht)", Numbuh 2's little brother, Tommy, trying to avoid taking a bath, finds himself on a ship with a captain who fears ever becoming clean. It turns out that he and his crew on the run from a giant rubber ducky who will make sure they're washed up if it ever catches them. In "Operation: D.I.A.P.E.R. (Drooling Infants Awarded Perilous Emergency Rescue)", Numbuh 1, Numbuh 2, Numbuh 3 and Numbuh 4, thinking that the babies at the hospital are being imprisoned so they can be turned into adults, 'rescue' them (despite Numbuh 5's objections). But it turns out that the babies aren't as helpless as they seem.
