April informs Ron that she is about to move to Washington with Andy to take on a new job. Ron tells her that she has to return him the key to his house. April realises that she has changed the hiding place of the key, and that she left a trail of clues, the first being 4 human teeth and a Twilight ticket stub. She and Andy tell Ron, but Ron is very excited to solve this mystery. They first visit Donna, who informs them that she and April watched that movie together years ago, when April removed her wisdom teeth. Donna also informs them that April also visited the shoeshine stand that day. The trio runs to the shoeshine stand, only to find that it was removed during the remodeling of the city hall. They visit the basement and they find Harold there, who tells them that a ghost took it. Ron realises that the ghost is actually councilman Milton, and they find him in his office polishing his shoes. They locate a note written by April to Andy, which ends with 'woof woof', which seems to be a dead end. Back at Ron's office, April feels guilty, but Ron reveals that he changes his locks every 16 days, so the keys that April has no longer work. April suddenly remembers where she hid the keys: she buried under a tree that reminded her of Ron. Ron highly approves of this hiding place, because he too had buried some gold there years earlier.
