SpongeBob and Patrick are about to go to the beach until SpongeBob notices that his "key" is missing. They transformed themselves into SpongeLock Holmes and Dr. Patson. Inside SpongeBob's house, SpongeBob is searching for the key using his magnifying glass while Patrick licks his lollipop. In the bathroom, SpongeBob and Patrick look in the bathtub and sink for the key. SpongeBob suddenly finds the key on Patrick's body when removing his clothes. SpongeBob asks how did Patrick get wet and sticky. The short ends with SpongeBob and Patrick looking confusingly while Dr. Patson's head in the toilet says "Intriguing."
