A first introduction to all the colours of the Island of Sodor with Thomas the Tank Engine and his colourful engine friends. Meet the engines and then spot objects of the same colour in the pictures. Each mini-book is shaped as an engine on The Fat Controller's railway - perfect for little hands! Children will enjoy learning their colours with the books and then making up their own exciting adventures as they chug their engine books around! Featuring: Thomas, James, Percy, Toby, Duncan and Diesel.
