I went on the seed Generator and typed in, "isawalolcat" I spawned on an island made out of Gravel and sand, and when I traveled inland on the ice I found Coal and Iron Ore that spawned on the surface. It's sort of snowy and has a lot of trees. Pretty easy to survive, eh? I hope you guys have fun on it.
How am I supposed to know it would do that?
Yes, a ton of trees, but only inland do you see trees.
