Put the 18 wooden pieces together to create an enchanting underwater picture and a puzzle that moves! With this innovative and unique puzzle, the pieces fit on the pins of the wooden puzzle board. This creates three interlocking gears that rotate when the puzzle is finished. For easy identification, an enchanting sea picture is shown on the puzzle board. Bright colours and a variety of marine animals encourage counting and colour recognition. The gears are ideal for developing fine motor skills and for learning cause and effect. Puzzle games help promote logical thinking, goal setting and patience. The Melissa & Doug Underwater Wooden Gear Puzzle is an engaging, practical and screen-free activity for children aged three and up.
