When some of the children in the park invite Barney to join them for a race, BJ and Baby Bop decide he’ll need their help. They show him several ways to get ready for the big race by warming up and stretching. By the end of the day, everyone finds out that there are many fun ways to exercise. When BJ starts to feel sick after eating too many sweets, he lies down in hopes of feeling better. He has a dream about a snack fantasyland where he eats as many sweets as he wants and ends up with a big stomachache. When he wakes up, he’s happy to find out it was only a dream. When he asks for a healthy snack, his friends are happy to oblige.
