I planted a bunch of different squashes but my MIL didn't use the labels when she transplanted them so I'm not sure of the varieties. One of them I thought for sure it was a pumpkin, but it looks a lot like it might be tetsukabuto pumpkin, but the skin isn't as bumpy and it doesn't look exactly like the photos of tetsukabuto that I've seen.

here's a photo:

Does it look like it is ripe? How do I know when it is ripe? This one is pretty good size. I'm dying to try it but I don't want to pick it too early.
