It's a warm, sunny day and Barney and his friends are soaking up some wonderful fun. When Robert wishes that just once he could stay up all night long, Barney uses his special "Night Timer" to create “night" during the day. Join the kids as they brush their teeth, put on their pi's and get ready for a long "day's night, compliments of Barney. They discover that nighttime has special sights and sounds all its own. Later, the stars begin to fade and the sky is all aglow with the morning sun…another Good Day/Good Night with Barney.
