Bob's Great Green Book is packed full of little things that little ones can do to help save the planet! Young children will watch in wonder as they fold out the book's sturdy, petal-shaped pages to make a giant sunflower! Plus, children can use the press-out seed markers when planting their own sunflowers - and watch them grow as tall as those in Sunflower Valley! With a different 'green' idea introduced on each petal page, children will learn how to look after their planet, recycle things around the house and reuse things rather than throw them away. Garden with Wendy, tidy up with Muck and reuse rubbish to make new things with Bob and his machine team in Sunflower Valley!
