12 months & up. Introduce children to different colors, animals, and shapes with the Magnetic Hide & Seek Farm Animal Puzzles! Designed with infants and toddlers in mind, these puzzles offer an engaging hide-and-seek experience. Each piece has a smaller, identical piece within it. Take all of the small pieces out, and encourage the children to match the small pieces with the big pieces based on characteristics such as color and shape. Magnets hold all of the animals together, and each parent piece measures approximately 2.25"L x 2.25"W x .75"H.
