Barney shows the children his new “Vend-O-Ball” machine.  When a button is pushed, it dispenses a variety of balls. Barney tells them not to push the red button it’s not working properly. Barney and the children do warm-up exercises with balls. They are joined by Baby Bop, who wants to play ball games, too. The Vend-O-Ball allows the group to share a giant cage ball, try some bowling, and even do a bit of miniature golfing! But when Barney and the children are busy elsewhere, Scooter talks Baby Bop into pushing the red button...and colourful chaos ensues!
