Hot Wheels Boy

It's official. Jasper declared this morning, and re-asserted tonight that he is, indeed, now a "Hot Wheels Boy". No more Jasper the Boy in this house, oh no. He is a lean, mean racing machine. Hot Wheels cars in the bed, Hot Wheels cars in the school bag, and of course Hot Wheels cars playdates with the also Hot Wheels crazed Afonso (in fact, I think Afonso might have started it all). On another note, I am really stuck on a Birthday party theme for Jasper this year. Can anybody help?
