You can get a lot of free things from the Treasure Room but only once a day. Go to the Tanglevine Jungle, back to the ruin area.. Then rub the head. I would recommend getting friends to help, it takes a long time.
After you get the head open you will play a jumper game and a game of blocks.
After you have finished that you will enter the treasure room. You only get to pick one thing a day, so I would look at all three chests before you decide . This is where you can get those long flowing skirts you see all the gals wearing.
