okay so i've been wondering what this is? i've had it forever and i don't know why it's still there after i made a island

 

I don't know, I think its a rare.

 

If I am not mistaken, that is worth about 30-35 grass. Could be wrong so don’t quote me on that.

 

These are worth SO SO SO much, it's a cobble, right? Yeah those are worth quite a few dcs and books are worth like 35 grass.

If you look at this thread triggered just closed, he was selling the exact same thing and sold it for over 3k grass. It’s a rare and is worth a lot!
