As we head on inside, we find Blue chasing a firefly. Steve welcomes us in, saying that we should be here for the pajama party. He's ready, he has on his green-striped pajamas and bunny slippers. Of course, it wouldn't be any fun if we just went right to sleep and Steve certainly seems to think so; he insists that he's 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're awake at night and then rest during the daytime. Later, Steve thinks of a deep question: Just why is it that we have night? After the Mail time segment, Blue and Steve became Pajamanauts and skidoo into outer 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 1st episode where the setting takes place entirely at night.
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 2nd episode to have Steve & Blue floating in Outer Space in the Skidoo segment.
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."
After the credits fade out, they just get to the back of the book and it closes.
