For this castle you will need two cardboard cereal boxes. First, cut three rectangles of different sizes out of the first box. Glue the short edges of the rectangles and make three cylindrical towers. Take the second box and cut three circles out of it. Make one radial cut on each circle, glue one side of the cut and make three cone-shaped roofs. Then make small cuts along the top edges of the towers and fold them outwards, glue them and attach the roofs on top of the towers. Paint the walls, roofs, windows and doors. After dried up, paint bricks.
