So Ive made my way though the mine and i cant seem to find any way of progressing further. Theres a man who told me about radishes, that i cant seem to find, and lots of locked doors i cant find a key for. So could someone point me in the right direction please?

There's a book inside the guy's house that might help.

I gave the slime a radish, and got a key. The first door I opened led to another radish and a television (which I sold), but there were no keys in that area. When I encountered the slime again, I gave it a radish, but the Tikiman in the room didn't give me a key. So where do I get a key at?

The door you opened to get to that radish and the tv (which you shouldn't have sold) Go up one flight of the stairs and down one to get to the lever to open the porticullis, (sorry not much detail) then there will be one room with the key laying on the floor and the next room has the key in a chest but I am stuck on how to get to the flmaethrower tikis... help for me?
