Such a small picture, but looks like a squash

Sorry, I was having trouble getting the site to accept the photo size. Here it is again:

Hi,
It looks like a cross of squash that happened in your garden, or you grew a hybrid. Either way odd new squash will appear this year. It happens quite often. If you remember what varieties you grew last year, you can figure out who the parents are.

Hi: Just wnted to add my two cents worth but too me your picture displays the characteristics of an ornamental gourd. Not sure but I would venture to say a gourd. Ross.

Ross,
Ornamental gourds are actually squash(Cucurbita pepo.) There are gourds that are a separate species(Lagenaria siceraria) like birdhouse gourds are. Often when a couple of squash that are of the C. pepo type cross like possibly a yellow summer squash and an acorn squash, they end up looking very much like ornamental gourds as in Mrsmig's pic.

Thanks for all the input. I haven't grown squash in my garden in years - the last time it was basic yellow crookneck. I'm guessing that the seed either came out of my compost bin (where I have composted gourds/ornamental squash in the past), or was transferred to my garden by an obliging bird.

In shape and color, the fruit on my plant is someone reminiscent of Carnival squash. I have noticed that my larger fruits have developed ridges and some warts. Has anyone grown Carnivals before, and do they look anything like my plant's babies before they mature?
