Indestructibles is the unstoppable book series made for the way babies "read": with their hands and mouths. And now the bestselling series  which ships over 1 million copies every year  is welcoming three lively new additions featuring a new artist, Vanya Kargulj, who brings an especially vibrant and charming sensibility to the series. Her colours are strong and pop on every page, and the faces are joyfully expressive. Happy and You Know It!is based on the perennially popular interactive song, often one of the first a baby learns how to respond to, making for endless hours of kvelling. Clap your hands! Stomp your feet! Shout HOORAY! It never gets tired.
