It's bedtime for the five little ducklings. The first little duckling says, "Okay. It's been a very busy day." The second little duckling says, "Come on! Let's go and put our jammies on." But when the fifth little duckling says with delight, "I'm not going to bed tonight..."--the smooth-running train to bedtime is temporarily derailed. However, a little cooperation from the ducklings and a little love from Mama duck soon set things right for a happy, snuggly night.
