Squash, squash, and more squash!

I took some unknown squash seedlings that emerged from my parents compost heap and placed them at various locations in my garden and yard. you see, my parents have a significant garden with many varieties of squash. It seems that squash will cross-pollinate and produce hybrids. I've ended up with quite a few interesting varieties of squash; at least seven unique varieties thus far. Here are a few pictures of our "hybrid" squash. I plan on cooking and eating the larger varieties just to see how they are. As a side note, I am also growing standard summer squash, zucchini, spaghetti squash, and acorn squash.
