Barney introduces the kids to his Vend-O-Ball Machine. He tells them they can press any of the yellow buttons because they dispense various types of balls, but nobody is to press the red button on the bottom, because it has a problem. The kids take turns pressing the buttons and learn about different ball activities such as bowling and golf. Scooter, curious what will happen if one presses the bottom button, asks Baby Bop to do so, and it dispenses so many balls, all the kids come to clean up, and Scooter apologizes for causing the chaos.
