Errors

 * During U.S. airings on PBS, the opening title card is narrated by Ladonna, and she narrates, "Arthur and the Haunted Tree House, Part 1", but there is no Part 2 title card later on.
 * When Ladonna is getting ready to leave Arthur's house, the pink sweatshirt from Mrs. Read that she is wearing briefly turns green.
 * The kids talk about "the other walkie-talkie", suggesting that there are only two. Yet, in the end there is one in Ladonna's backpack, one in D.W.’s bed, and one used by Buster respectively Arthur to do the voices.

Episode connections

 * Halloween also takes place in the episode "Hic or Treat". As such, Arthur, Buster, Francine, and Mr. and Mrs. Read all have the same costumes.
 * However, Arthur's costume is white instead of green.
 * The Brain is seen wearing the bear mascot costume from the Ice Cream Shop in "Brain Freeze".
 * Mr. Haney wears a Louisianan face mask, which is seen again in "Muffy Misses Out".
 * When Arthur goes up to the attic near the beginning of the episode, a copy of "The Mysterious Hand" can be found in the foreground. This was the primary book featured in "Arthur's Lost Library Book".
 * When Muffy recollects walking through the cemetery with Francine, a gravestone can be seen with the writing "YOMAMA". This is a reference to DW's humorously incorrect pronunciation of Yo-Yo Ma in the episode "My Music Rules".

Production notes

 * It is one of two hour-long specials produced as part of the Oasis Animation production deal (alongside Seasons 20 and 21); the first being D.W. and the Beastly Birthday.
