You begin looking at the black external wall of a home of some sort. Turn far to the right and move towards the open door on the same home, but before you get completely to it turn right again, and move up the four steps onto the porch of the red home, next to the rocking chair. Once you are there, crouched down by the rocking chair, presumably getting ready to crush a walnut under it, or something of the sort, you are done.
