Personally, I think it sounds like a fun premise and possibly fun episode. The only thing that really makes me skeptical is my own....distaste for Cheese. While I don't despise the character, I think he gets far too much air time already. However, I can say that I have wanted to see more interaction between him and Bloo, and so I'm actually somewhat optimistic about that.
Let's hope my optimism punches out my cynicism on this one.
