The Fetch! With Ruff Ruffman Season 5 Premiered earlier today! So if you missed it let me give you a little recap. Basically it was the official start of the new season which meant Ruff Ruffman needed to get a new cast of Fetchers together! I am not going to tell you any more. To find out who the new Fetchers for season 5 are you can go to pbskids.org!
