If you go in the entrance that does NOT have scary mary. Stay left.. at one point there will be a very large rock splitting the path the dig spot is in an area on the left, at the far end of this rock. Theres a small opening protected by a terror wasp moving back and forth, its in that area. You can usually run past the terror wasp, it should leave you alone if you dont attack it.
