3 Magic Balls

Uncle Dinkleschmidt agrees to buy three rubber balls for his toy store from a woman with a pointed hat. As she hands the balls over, she also hands a gold whistle to young Rudy. What would he do with a gold whistle? When his uncle leaves the shop, Rudy discovers that the balls come alive and they lead him on a great adventure. Bouncing, bouncing, bouncing the balls go merrily about the city until a plane appears in the sky and is close to disaster. How far can you go with your own magic?
