Supporting Cast




  • In Japanese, Obake Yashiki (おばけやしき) means "Haunted House". The title refers to both the haunted house from the episode, as well as Obake as a character.
  • The episode is Halloween-themed.
  • Baymax is seen in his pirate costume from the "Baymax and Fred" short.
  • Honey Lemon's Halloween costume is Lenore Shimamoto while Fred's Halloween costume is Captain Fancy.
  • The team's fears are revealed in this episode. Honey Lemon has a fear of hippopotamuses, Hiro is haunted by the memory of his brother's death, and Go Go has a fear of leprechauns. Fred's arachnophobia was already revealed in "Fred's Bro-Tillion" and "Mini-Max", as was Wasabi's acrophobia in previous episodes. Baymax is the only one with no fear due to him being a robot.
  • The episode features a brief flashback of Tadashi's death in the film.
    • In the film, when Tadashi died he wore a black shirt, but in the flashback and throughout the episode he is seen with a white shirt.
  • Fred's quote "I find your lack of fear disturbing" is a parody of Darth Vader's quote "I find your lack of faith disturbing" from A New Hope.
