In this whale of a tale, the Big Bad Shark is looking for a tasty snack... when he comes across three delicious-looking narwhals! The loveable, pointy-horned creatures-show-off Spike, arty Spiral, and shy Stubby-discover a sunken pirate ship, and are using the parts to build their own homes. Now they are out of their depth, locked in a battle of wits with the munching, crunching villain.
