Which of these is not a type of hybrid pumpkin?

I have such wonderful childhood memories of carving a jack-o-lantern with my Daddy. He wasn't the type for playing games or getting involved with activities but he always did the pumpkins...it made it more special. I've tried to carry on the same tradition with my children but it doesn't seem the same...

never seen pumpkins carved like this . love it !

I am first to comment and I am at a loss for words!! Thanx for the info on pumpkins, it was interesting!! Give me some Greek Mythology, if you can!!! Thanx for such an outstanding game!!
