Down by the pumpkins, where nobody goes,

Is an odd little squash that nobody knows.

Did he come in the post or the back of a car?

All I know is he’s a new rising star.

Built like a tank with no care for another,

If there were but two, then he would have a brother!

He’s larger than most and his skin is bright yellow,

Can someone identify this little fellow?

With a photo and poem to boot, can anyone out there tell us who our unnamed guest is?  He’s clearly a rogue seed from either my Jack Be Little or Crown Prince seeds, but who is he?  Any help would be gratefully received! (Please excuse the bug poop on him!)
