The basic story of Parappa 2 is the son of the owner of a fast food restaurant forms a "cult" that pretty much worships noodles. The "cult" attempts to turn everything in the world into noodles and you have to stop them by rapping. I know your probably thinking what the ****, but believe me, it is a VERY fun game.
This game is very short (eight very easy levels), but is strangley addicting, despite the really easy difficulty. I recommend this game to any gamer, of any age. Even gamers who can't stand easy games will like this one.
