Alexander Claffy, the voice of Purple Kangaroo, and Danielle Gonzalez, relative of Animator Dayna Gonzalez are both friends of Steve in this episode. Felt frame picture: Felt Friends taking a bath (Same thing as What Does Blue Need?) then Felt Friends gets toothbrushes

The usual Blue's Clues instrumentals are replaced with a different kind of music to go along with the quiet version of the Blue's Clues song. This is the debut of the improved version of Steve's hair from Hide and Seek, but this time, his bangs were added again.

The lyrics to the So Long Song have slightly changed in this episode, "But we'll sing just one more song" has changed to "So we'll sing this goodbye song", "Thanks for doing your part" has changed to "Thanks for coming tonight", "You sure are smart" has changed to "You sure are bright".

This is the last produced episode where the pawprint is still shown on the third clue after Steve draws it. The Mailtime barbershop quartet singing is the same as the other episodes, but it has a quieter nighttime arrangement rather than the regular arrangement. This is the second episode in the series to have rare bonus scenes that are hardly seen, the first was Blue's Birthday, where the bonus scenes are shown in the VHS version.This is the first episode that does not show Blue playing with her rubber ball at the end of the credits before the book closes. In the Duarte version, this nighttime version of the notebook is used throughout the whole episode.

Sidetable Drawer was asleep by the time Steve went to get the nighttime notebook. When he did, she muttered her original quote: "Blue's Clues, I'm so excited." in her sleep as she opened her drawer so Steve can get the nighttime notebook.Unlike most episodes, Steve and Blue sing the usual songs quietly because they had some sleeping friends inside so they would not disturb them. The second is Blue's Big Musical, which had the credits in front of the red curtains written up in cardboard text.

When Steve and Blue skidooed into space, Earth made a complete spin. So when they returned, it should not have still been the same night; however, it was. In the U.K. version, the moon appears a fifth time with her first quote, due to part of the music being used again. As usual, the U.K. doesn’t like to use the unusual short credit lengths.The fourth (third if you don't count the three-episode Season 4 finale) was the Season 5 episode special 100th Episode Celebration. During the credit sequence the moon appears four times; It said "Bye" twice and then "Good night" and finally a "bye-bye." There were 2 bonus scenes that features special guest star: Julia Louis-Dreyfus that only appears exclusively in the opening and post-credits scenes in the original airing.

This episode does not end with the reversed scene of the door closing and Blue waving goodbye to the viewer in the left window, Steve quietly sings The So Long Song in his bedroom instead of the living room, and Blue does not join in, or show up at the window to wave goodbye to the viewer in one of the windows because she is sleeping in her bed, and it ends when Steve turns off the light.
