Thomas & Friends™ Wood toy train sets now have kid-friendly, easy-to-build track. The revamped track connectors fit together easily, allowing children to build layouts – and stories – by themselves. Our unique connectors offer a sure fit every time – there's no wrong way to connect, so there's no wrong way build! Plus, the Big World Adventures™ Set comes with two track adaptors that are compatible with other wood track systems, including BRIO, Melissa & Doug and others (each sold separately and subject to availability). Children can embark on the biggest adventure of all as they travel the world with Nia™! With so many places to see, and new friends to make, the story possibilities are endless. From India to China to Australia, you can help Nia™, Isla the Australian rescue plane, and the doctor aid people and animals in need of rescue! Destinations include the Monkey Palace in India and the Great Wall of China. The set also includes a doctor figure as well as crocodile, monkey and kangaroo animals. There's even a rescue carriage that Isla can lift with the magnet beneath the plane! For a seamless playtime experience, Thomas & Friends™ Wood trains and vehicles are also compatible with classic Thomas & Friends™ Wooden Railway track (sold separately and subject to availability).
