As Arthur tries to prepare his costume for Halloween, he finds himself distracted by D.W.'s persistent case of hiccups.
- D.W. imagines her future self as the same size but with white hair, despite imagining her future self as an adult in "D.W.'s Name Game."
- D.W. is still scared of octopuses, as revealed in "D.W. All Wet."
- D.W. gets the hiccups in "Arthur vs. the Piano," which has a similar ending gag.
- Halloween also takes place in the one-hour special "Arthur and the Haunted Tree House". As such, Arthur, Buster, Francine, and Mr. and Mrs. Read all have the same costumes.
- When discussing D.W.'s fears, she says she has never seen Dark Bunny, but heard it's "scary." However, in "That's a Baby Show!" she says she watched it the day before and it scared her.
- In the title card, D.W.'s dress is colored orange and Arthur's pants are colored green. This is because the episode takes place on Halloween and orange and green are colors commonly related to the holiday.
