Blue's Big Pajama Party is the sixth episode of Blue's Clues from Season 3.
Steve and Blue host a Pajama Party.
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 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. 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 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.
