Soup and Rob have a plan. Their new friend Piffle Shootensinker, a seven-foot-tall European basketball star from Pretzelstein, has just moved to town. Piff has a problem. He's homesick, he misses his dog, and can sink a basket only when he hears the music of his homeland on the spitzentootle. What's a spinzentootle? It doesn't take Rob and Soup long to learn. Can they locate one (and also find a dog) in time to inspire Piff to lead the Learning Groundhogs to victory?
