A silly shark and lobster are in a panic to ward off a land-bound menace in this comical ode to the power of suggestion, the joys of teamwork, and the fun to be found in a narrow escape.Out in the sea, Shark told his friend Lobster one day: "Lobster, I'm scared!"What could Shark possibly be afraid of? It seems somebody's told him about a thing that's full of teeth and stripes, and now he's scared of . . . tigers! Rumor has it these horrible creatures walk on their teeth, glow in the dark, and eat you up. Of course, there's nothing to be done but to build an undersea fortress that will shield Shark and Lobster from this terrible threat, and as word gets around, ocean friends from cuttlefish to spiky crabs get busy piling seven hundred rocks and an old piano to keep tigers away. But is their wall high enough to do the trick? Wouldn't a huge sea monster, big enough to swallow them all, do an even better job of protecting them?
