Shark Island (Young Puffin Developing Reader)

Penk the penguin is marooned on Shark Island with nothing to eat but a box of bananas. How on earth will he get home to Penguin Bay when two sharks, Slasher and Sluggit, are just waiting for a chance to have a snack of tasty penguin? But help is at hand in the form of Penk’s great-uncle, the Penguin Rescue Ship and Doris Shark, Slasher and Sluggit’s mother.
