Simply add water to bring cute and cuddly monsters of all shapes and sizes magically to life. Filled with simple, black-and white images of every type of fun and furry monster you can think of - and lots you can't! Just use the brush provided to sweep water over the designs and rainbow hues magically appear. Great for keeping little ones busy and helping them to learn brush control skills at the same time. Perfect for travel. 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.
