Count, stack, match and discover multiple ways to play with Thomas and Friends. Percy Stack-a-Track from Fisher-Price combines the fun push-along action of a toy train with three other beneficial forms of play - counting, stacking and matching. Toddlers can take the separate play pieces and stack them to form a complete, rolling Percy train. They can also match and connect the play pieces in a straight line to form railroad tracks with adorable images of their favorite Thomas and Friends characters. Plus, the pieces are numbered one through five, so children can practice counting and number recognition as they stack their engine or match and connect their track pieces.
