I’m assuming you’re a dice hoarder like me? Pour all your dice into a pan and vibrate it as fast as you can without spraying dice all over the place. That’s what it looked like, except it mainly chose to take the form of an quadruped because that’s what it thought looked prettiest. I think it was trying to kill us because it thought bipedal creatures are ugly?
