The order is randomized each playthrough, so you’ll have to do a bit of guesswork and start by finding which blocks match the two rows on the edge of the puzzle box, and work your way inward. The sides of the wooden box also have two half shapes - and you need to match both rows of shapes by swapping blocks around. Each block has several shapes on each side: Squares, Circles, Triangles, and Stars.
Look around the room and you’ll find a Toy Box in the corner with three other Picture Blocks already in place. Inspect the doll, and look on the back to find a zipper that conceals a Picture Block You’ll have no items or weapons of any kind to speak of, so start by investigating the Bedroom for a big Stuffed Doll toy on the nearby chair.
