I bought exactly one new squash this year - spaghetti. The first pic is what I am sure is spaghetti squash. The second I have no idea/ My notes said it was cougar F1 but that is not right. It looks like nothing I have ever grown before. The leaves are a lot bigger then the spag squash. This seems like I got a different seed in the package except, nearby, I have a second plant that is exactly the same! I grew a lot of squash last year and there is a remote chance a seed sprouted - but at exactly the right time as when I expected ones I planted to emerge and exactly those 2 spots and nowhere else seems nearly impossible.

I have also grown vining Squash: acorn, gold rush, buttercup, tableace

Mystery?
