tunneling dunes

a rare desert boime varient where there are small sand worms (or what you want to call them) and they pop out to bite you and deal damage, you fishing rod them to pull them out of the ground where they flop areound. they do not break blocks, they pass through all blocks exsept mud. also there are giant tunnels through the hills. also structures with chests made of mud. and if you dont add it, at least add my name somewhere hidden! -Porter
