Build a big railway celebration with an all-new Thomas made just for little engineers! Thomas is feeling festive! Made just for the youngest Thomas fans, now you can build a special celebration-themed Thomas when you use the big blocks and rolling wheelbase to bring Thomas to life — complete with fun party balloon decoration! Whoosh around the island of sodor and send Thomas out for the big occasion. Or connect him with other buildable engines for even more friendly fun on the railway! Ideal for ages 1 to 5.
