bigger what

So as it grows all the hairs fall off and it becomes far more round. I'm a bit stumped and hoping it is indeed something edible!

My husbands guess is watermelon. I have no idea!

I'll back your husbands prediction.

[Peter Grave]

No idea.Take or send a picture to the DPI for identification.

Can't help as to what but it is interesting watching the growth through you pictures.

[Rick]

Almost looks like a watermelon, but don't believe they have the hairs.

[Chris K]

[Valerie Chesney]

Can't help either, but, post a shot when you cut this fruit open, would so like to know!
