There's a campfire, a box with 'Mint' on it (Orbit maybe), Block Man staring into window, a huge key, Captain Obivous' Chest, a metal hammer, a manhole and a poster with a screenshot of a man skiing in The Slopes. Oh, and and strange blinking on the floor.
What will you do?
Hint: That fire is over 9k degrees of heat.
