Butternut Squash Oddity

The pictures below are not of anything I grew myself, but rather an organic butternut squash that I bought from one of our local shops.

The pictures may look a bit gruesome, but these are the seeds and the rest of insides of the squash. We were amazed to see that some of the seeds had sprouted and were growing inside the squash. I've never seen anything like this before.

What's really interesting is the way the seedlings are greening up even though they had not been exposed to light before the squash was cut open.

Amazing!
