Two different fruits from the same vine? Is it possible? The light color oneooks like the spaghetti squash I am growing. The green one looks like some kind of zucchini, although it looks stubby.

Old news.

Maybe crossed seeds. Not only do you get strange fruit from crossed seeds, but I believe sometimes you get different fruits from the same vine if the hybrid isn't stable.

Amazing!
