Fetch! With Ruff Ruffman

Ruff's Bowling Is Going Downhill

Willie and Bridget go on a quest to build a bowling machine. First, they meet up with an engineer to learn about the physics of bowling. Then, the kids put their knowledge to use, designing and building a machine that can bowl well. After testing and refining their machine, they use it to compete against "Throbot," a multimillion dollar bowling machine. Meanwhile, Rosario heads to the mountains to learn how to snowboard.
