Filled with simple, black-and white images including a T. Rex, a Diplodocus, a Triceratops and many more. Just use the brush provided to sweep water over the designs and watch vibrant colours magically appear! Great for keeping little ones busy and helping them learn brush control skills at the same time. Simply tuck the waterproof back flap under each page as it's painted, to stop water from seeping through to the rest of the book.
