Hi Everyone!

I was hoping that someone might be able to tell me what kind of summer squash this is. I grew it from seed from a "Summer Squash Mix", and I'm not too sure what kind it is! I have all sorts of different summer and winter squash growing in the same garden, so maybe there is some cross pollinating going on here? It is about 4-1/2 inches in diameter and 3 inches tall. Oh and excuse all the scratches on this poor guy, my 3 year old got a hold of him.. So anyway - if anyone can tell me what this is, and why it looks like a Giant Pumpkin growing, that would be fantastic! Thanks!
