You begin looking at a large stone archway. Go ahead through that archway near the easel on the left. The easel that is near a unicycle. Ooh boy... Pass by the easel and onto the stairs to the left. Go all the way up those couple of steps, and then take a step forward. Not the decapitated Lego head on the pallets to the left, but then turn fully right, step across to the top of the other stairs, and then move down onto the stairs that were on the right initially. Once you are halfway down the stairs, you're done.
