P’kolino’s Puzzle Stacker increases the play value of the classic stacker by adding the benefits of puzzles. Stacking toys help develop a baby’s hand-eye coordination and recognition of sizes and colors. The puzzles fine-tune motor skills and teach spatial logic through joining the interconnecting pieces. This two-in-one toy does both, doubling the fun; and doubling the development. Also available in a 6 ring version. Launch date: June 2009.
