Two delightful and challenging 3-Dimensional puzzles. Our wood puzzle snake (21 pieces, 15-1/4" long), and a wood puzzle whale (17 pieces, 12-1/4" long) will come apart one piece at a time. The challenge is to figure out the correct sequence to reassemble the pieces. Each is a special and whimsical gift for any age. Wonderful conversation pieces to display on any table or shelf.
