Unbelievable!

I am just about finished Christmas shopping for Big Boy and it isn't even Thanksgiving yet! I'm sure I will pick him up a few more things here and there but at least I know for the most part he is finished. I'm not really sure we'll be doing the "big ticket" item this year. He doesn't really need anything. He got a bike for his birthday. Any ideas, suggestions, on what to pick up for a three year old terror?
