Start by building the track configuration shown on the box. Explore the track solving the puzzles and making music as you go. Put the triangle, rectangle and semi-circle in the Shape Sorter Track so the train can pass. Then solve the bead maze. Listen to the beautiful melody as you drive over the Xylophone Melody Track and happy ringing of the Tambourine Track. The six building blocks have fun optical features including a mirror, prism and magnifier.
