My guesstheory about pony level =D!

You know these mobs that spawn gold and escape in some kind of yellow portal? My guess is that we'll be able to access it somehow using that. No idea how this will work out, but it's my guess haha.

That portal leads to the goblin realm me thinks. There has been a thread it.
One cannot enter the portal though :(
At least not in the beta.... DUN DUN DUNNNNNNNN
