The 7D Episode 11 Bathtub Bashful / Knick Knack Paddy Whack >The 7D bring an oyster that has a Pearl of Wisdom for Queen Delightful. Lord Starchbottom stores it inside the Knick Knack room, but tries to avoid saying "Knick Knack" because it prompts Delightful's to sing the related verse from "This Old Man" and he would have to roll down a hill quoting "This old man came rolling home." In order to win a fancy cloak, Hildy and Grim must answer a riddle without consulting the Crystal Ball, so they steal Delightful's oyster but are unable to open it. The 7D try various methods to distract the Glooms so they can recover the oyster.
