Thomas & Friends Railway Pals vehicles and train sets deliver fun-filled play that encourages development in toddlers through motor skills, thinking skills, academics and imagination.  These adorable engines interact with the track activation points found on Railway Pals train sets (sold separately and subject to availability) to deliver sounds, music and phrases that introduce letters, counting and colors.  Press Percy's light-up bumper to hear him teach children about the letter 'M' for 'mail', the color green, and the numbers 1 and 2.  Toddlers can also roll him over activation points on Railway Pals interactive train sets (sold separately and subject to availability) for even more educational sounds, songs and phrases.  Plus, as children grasp Percy, roll him along, and create unique adventures, they're engaging in play that promotes motor skills and imagination.  Collect all the Railway Pals vehicles and interactive train sets to build a rolling, talking, singing world of educational play! (Additional vehicles and interactive train sets sold separately and subject to availability.)
