SLOTHERAK'S PROFILE

I can't get the Rusty Key, and survive the dog/demon/wolf thing long enough to get outside. I have the Rusty Shovel, Sulphur, Mushrooms, Orb and Lantern. I assume that the recipe in the alchemist's hut implies that the Mushrooms and Sulphur are added to a third ingredient to make the acid, but I can't find any bone meal. I also have found a small collision glitch, where I can go into the South-East corner of the North-West building, where it's clearly supposed to be a solid wall.
