Adventure time trivia: Candy Streets~ When the cats are in the suits with a suitcase, this is similar to the character, Business Cat, from Our New Electrical Morals. In the Candy Drugstore behind Ann there is katakana (Japanese) on the glass that reads “ファーマシー”, meaning “pharmacy.”
When Ann is getting the empty jar down, on the far right of the screen, there is a bottle with Viking ruins on the label; they possibly spell out “Eelaei.” Viking ruins are also on the yellow carton next where the jar was sitting; they possibly spell out “Apreil”.
Jake turns into a pipe that Finn inserts into his mouth. This is a reference to Sherlock Holmes.
Several connections to “Mystery Train” appear in this episode, including the return of the Candy Kingdom’s train system (and many of the former passengers) and Jake transforming into a person (such as he did as “The Conductor”).
When Jake stretches into a lawyer, the form resembles the Business Men from the episode “Business Time.”
