My first dorodango
It's not supposed to be this rough (I made it from too gritty baseball field soil). It's literally made by just forming soil into a ball. You keep on polishing it with dry soil and your fingers until it forms a rock-like outter layer. It's very dense and heavy. I showed it to a couple of people yesterday and they couldn't believe it wasn't a painted rock. See here for instructions (which I didn't follow too closely enough).
