Mining World Mobs

[ShinyPorygon]

As most of you know at spawn there is a portal to the Mining World or as I call it the Mining Overworld. Since this is in theory a second overworld all the structures and what not will generate however no hostile mobs can spawn due to settings. I think it would be nice to be able to have hostile mobs spawning so that we can find the guardian and elder guardian since the only ocean temple in the normal overworld is claimed...
