Big Bird is very excited to go to sleep in the new pajamas that his Granny Bird gave him. Gordon goes to tuck him in and say goodnight, but as he is walking away, Big Bird complains that there is something bothering him in his nest. When Gordon checks his nest, he finds a truck hidden inside. Gordon tucks him in again, but there is something else in Big Bird's nest that is still bothering him. This time Gordon finds the letter C, which they take out. Big Bird is still uncomfortable, though, and each time he calls Gordon back, Gordon pulls out more objects including a cactus, a number 1, and a pineapple. Gordon can't find anything else in his nest, but something is still bothering Big Bird! Just then, the Princess from the Princess and the Pea story arrives and explains that besides being a Princess, her other job is a sleep consultant - helping people who cannot sleep. Through scientific inquiry, she investigates and discovers a pea. Big Bird is convinced, though, that there is still something in his nest. Susan suggests that maybe Big Bird sleep in the cot for the night instead. Gordon sets up the cot and Big Bird lies down in his new pajamas. But once again he feels something. Finally, Gordon realizes that the problem is the tag in Big Bird's cozy new pajamas. He removes it, and Big Bird quickly falls asleep in his nest, as Gordon falls asleep on the cot.
