A plywood puzzle with a difference: the idea is to get the pieces out after you put them in. The 11.75-inch by 8.50-inch aquatic scene (mainly in blues, oranges, and browns) includes such pieces as a sea horse, various fish, a crab, and a starfish. Though the pieces are wood, each has a metal "button" in the middle; attach a magnet to a line and practice "fishing" them out before reconstructing the puzzle. (For an especially interesting challenge, try "fishing" them back in.) These interactive games are great for developing dexterity and improving hand-eye coordination, visual perception and fine motor skills. Each board has 10 removable pieces, game is recommended for ages 3 and up.
