Any idea what this is?? – Reddit Post

I planted a bunch of random seeds and got this with my pumpkins (side note I planted seeds from Costco pumpkins and got two massive ones!!) and got these. Some of the green stripes that were not facing the sun are orange. I have no idea what it is. Fireball pumpkin? Carnival squash? Mostly want to know if I can eat it or not since I have about 6!
