 * This is the first episode where Dot celebrated Halloween, but he has not celebrated Halloween with either of the three hosts because he was not introduced until Retsuko's Big Mystery and Our New Neighbor.
 * Even though Dot is introduced before Corrin became the host of Retsuko's Clues, no Halloween-themed episodes were produced during Corrin's tenure as host.
 * Robin is dressed up as a werewolf in this episode, he is seen wearing a furrier version of wolf ears from "Story Time with Retsuko", wolf paw gloves and a wolf's tail. he also howls like a real wolf.

 * Robin howls like a wolf at the end of the "Mailtime" song instead of shouting "Mail!". Similarly, Mario And Luigi, as a cow, replaces "Mail" with "Moo" and Robin calls him "Cow Mario And Luigi", similar to how Pit called Mario And Luigi as a monkey "Monkey Mario And Luigi" in "Animal Behavior!".

 * Dot as the ghost skidooed to Haunted House. This is the third time Dot skidooed. The first two times were Dot Misses His Friend and The Big Book About Us.
 * At the end of the Mailtime song, Robin howls like a werewolf instead of saying "Mail!", which is similar to Corrin saying "Goal!" instead of "Mail!" at the end of the mailtime song in Soccer Practice.
 * However, unlike Robin, Corrin corrects himself by saying "I mean... Mail!".
