Dillon, don't feel bad..I hear ya, I still have found one either and it's driving me nuts. Technically, the last Anniversary Kid on my wish list unless I find one other girl that I keep leaving behind, lol...
You know, I've kind of been noticing the same pattern around here by me, but just in general, not specifically with Bald #4's. I've checked several stores multiple times now and there's usually a few of the same Kids (same BC's), but I'll find maybe 3 or 4 mixed in that were never there before or 1 boy. Or a few will be missing and then reappear the next time I check. One day they'll have 4 Kids out, the next week there's 20...
