In this episode the focus is on Piers the puffin. Piers is on a mission. He's the ultimate all-terrain vehicle with an awesome beak. But our 'not-so-secret' agent has a lot to learn. He has to find himself a mate, secure a nest and learn the secret of catching 12 fish at once to feed his family. Life as a new recruit is tough, and Piers makes every mistake in the book! Will he escape the hungry seagulls and peregrines, and will his first chick learn to fly before winter?
