Instructions
Walk down the edge of the river until you find a yellow house.
Look for the side of the yellow house that has a large brick wall. Walk behind the wall so you face the wall, but your back faces the river.
Press the "Z" button on the Wii Nunchuk to attack the wall and knock it down. It will fall into the house and create a series of demolitions that cause pieces to fall across the river.
Jump onto the main wall piece. Follow the pieces of house across the river. When you land, wait a moment and time your next jump perfectly so you do not have to start over.
Jump on the last piece of wall on the river and then reach the other side. Find a save point so you do not have to repeat those actions again.
