Blue's Clues

The music playing during the Mailtime Segment was an instrumental version of "Things I Love to Do" from the audio version of "Blue's Big Treasure Hunt." The character Felix in this episode first appeared in "The Lost Episode!" and the "go back" song is also from that episode. Also, Felix is apparently voiced in this episode by somebody other than who voiced him in "The Lost Episode!"

Joe is wearing a green shirt in this episode.

Angela Santomero is credited as Angela C. Santomero. The list of Joe's Friends at the end of the episode includes "Trevor, of Dawn Animals." This is most likely the dog from the Mailtime segment and the character Trevor in the skidoo segment in this episode may (or may not) be named after the dog.
