Yep, that looks like a pumpkin to me. My granddaughter used to call them pumpmins. My grandson used to call them punkums.

My wife made a pumpkin halloween costume for him when he was a year old. She dressed him in it and took him to a pumpkin farm to sit him next to some real pumkins for a photo. I told her to be careful because he looked so much like a pumpkin, she might loose him amongst all the other pumpkins.
