As we head on inside, we find Blue chasing a firefly. Steve welcomes us in, saying that we should are here for the pajama party. He is ready, he has on his green-striped pajamas and bunny slippers. Of course, it would not be any fun if we just went right to sleep and Steve certainly seems to think so; he insists that he is not sleepy, despite evidence of yawning. So before getting ready for bed, we have some fun. After watching Mr. Salt and Mrs. Pepper put Paprika to bed, we head outside, where we find Shovel and Pail listening to the sounds of the night and playing a game called Nighttime Flash and Find. We learn that there are some animals that stay awake at night. We identify an owl by its hoot, a cricket from its chirping and a squeaking bat. All of these animals are nocturnal; they are awake at night and then rest during the daytime. Steve then finds the 2nd clue on a lamp. Later, Steve thinks of a deep question: Just why is it that we have night? After the Mailtime segment, Blue and Steve became "Pajamanauts" and skidoo into space, where they have a chat with the sun and the Earth and learn that the sun is always shining, but because the earth is always spinning, parts of it are in a shadow, away from the sun's light, thus causing night. After learning about night to day, they then skidoo back home, just as the late night approaches. He takes off his blanket cape and puts it back in place. He then finds one last clue, which is a book, sitting on a table next to the front door. He draws the clue and sits on the Thinking Chair. The answer was: reading a book. Everyone gets ready for bed as they were brushing their teeth and Steve reads a bedtime book called "Goodnight, Bird" to the others. After reading, Steve sings the So Long song in a soft manner. After they went to bed, the episode ends.
This is the first episode where the setting takes place entirely at night.
There's a deleted scene that features special guest star: Julia Louis-Dreyfus that only appears in the opening and post-credits scenes. This only appeared in the original airing. These can be found in https://www.youtube.com/watch?v=7XLuUKLAMVI
Sidetable Drawer was asleep by the time Steve went to get the 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 notebook.
This is the second episode to have Steve and Blue floating in Space in the Skidoo segment.
Instead of the page flipping and the white background with the navy blue letters, the closing credits for this episode are in bright yellow with a black, starry background.
During the credit sequence the moon appears four times; It said "Bye" twice and then "Good night" and finally a "bye-bye."
Also in this credit sequence, the ball and Blue don't appear, Blue doesn't wink at us and kick her ball and go before the book closes, after the credits fade out, they just get to the back of the book and it just closes.
This is the final television episode in which Jenna Marie Castle provides the voice of Paprika.
The lyrics to the So Long Song have changed a bit in this episode, "But will sing just one more song" has changed to "So we'll sing this goodnight song", "Thanks for doing your part" has changed to "Thanks for coming tonight", "You sure are smart" has changed to "You sure are bright".
The Mailtime barbershop quartet singing is the same as the other episodes, but it has a nighttime arrangement rather than the regular arrangement.
When Steve says sleeping bag three times, he yawns.
This is the third episode where Steve was shown yawning.
This is seventh episode where viewers say "Notebook!" from "Mailbox's Birthday" was not used.
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 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 episode does not end with the reversed scene of the door closing and Blue waving goodbye to the viewer in one of the windows, 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 because she is sleeping in her bed, and it ends when Steve turns off the light.
This is the first episode not to feature the end credits with a white background, it features them with a nighttime/space background, the moon appears 4 times, and after the credits fade out, it gets to the back of the book and it closes.
The second is Blue's Big Musical, which had the credits in front of the red curtains written up in cardboard text.
The third is 100th Episode Celebration, which had a red background with the yellow curtains closing before the Nick Jr. Productions logo.
This episode will be remade in the reboot, as titled Pajama Party with Blue.
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.
Steve sings loud in the middle of the Mail Time Song by accident.
