He's the hippest and probably coolest kid in the Wild Grinders, but is also a real germophobe. He tries to act all tough around his buds, but around his parents, he's unusually polite -- from tough guy to gentleman in a kick flip! If an old lady needs a hand crossing the street, Jay Jay steps up (as long as her hands are clean). Unbeknownst to most of the Grinders, Jay Jay is also exceptionally smart and taking college level science courses. You would be surprised by the things Jay Jay knows!
