Abby goes to Big Bird’s nest for her very first sleepover! She brings her wand, her pillow and her favorite book. Her mommy always reads a book to her at bedtime, but at Big Bird’s there isn’t anyone to read to them. Luis and Maria walk past on their way to go dancing, and Abby and Big Bird ask them to read the book. Maria doesn’t think it will take too long so she agrees. Before she can read the story, though, there’s a routine. Abby must brush her wings, sing the “Brush the Wings” song and get tucked into bed. After all of this, Maria picks “Hey, Diddle, Diddle” out of Abby’s magical book, and the story comes to life. Luis and Maria finally get to say goodnight and are about to leave when it begins to rain. Big Bird asks them to help get Abby out of the rain. The only solution is for Maria and Luis to invite Big Bird and Abby to have the sleepover at their house. To thank Maria and Luis, Abby’s mommy grants them a wish. They wish they could have gone dancing. Their wish is granted and the living room turns into a ballroom. Maria and Luis dance while Big Bird and Abby have the best sleepover ever
