Katie is almost always happy, but sometimes at night, when the Jibberwillies come and scare her, her mother must catch them in a bucket and throw them out the window before Katie can fall asleep.

In his cozy house on his cozy street, George slips into bed, but sleep will not come. He is afraid of the dark and wishes for even one small nighttime friend to help him. When a little mouse appears, a night of adventure begins. George meets new friends, like a piano-playing bunny with stage fright and a penguin afraid of water. He learns that everyone has fears, and good nighttime friends can help you overcome them all and have fun along the way!...
