Oh yes, many an hour of Castle Crashers has been played at my house, but they don't play it much any more. When my oldest was 2 (pre-divorce) I made him a Moogle costume (like Final Fantasy.) He was so cute.

I only have 1 picture of him in it. Then the next year when he was 3 (post divorce but only 1.5 months before becoming homeless,) I made him a knight costume. I was so poor. I just got a sword and shield and then did imprints from the shield into tin foil, and sewed it onto a black sweatshirt for the armor. That was the last costume I ever had any input in for him.
Hmmm... zombie is a good idea.... I don't want to be to scary though, for the baby.
It also gets cold here at Halloween. Sometimes snow but usually needs a jacket.
