FETCH! with Ruff Ruffman - Season 4 (2009)

Ruff's cameradog, Tank, is not the most reliable employee in the world, and Ruff is looking for his replacement. Meanwhile, Blossom informs him that pigs are actually smarter than dogs. Ruff sends Bethany and Brian out to prove Blossom wrong; and Sterling and Liza go to SeaWorld to see if Shamu could make a good replacement for Tank.

Blossom has organized her own FETCH challenge: Two teams of FETCHers will compete in a 50-mile race, and the team that emits the least amount of CO2 wins.
