The Art Of Ninjas

Have you ever seen a mysterious shadow in shape of a penguin, and wonder what it was? Probably just seeing things, you tell yourself. But as soon as you rub your eyes and look up again, the shadow is still there. It hasn't moved at all. You still try to convince yourself that it's just a figure of your imagination. No use, because it doesn't move at all. You look desperately at another penguin. "Can you see that strange thing up there?" you ask. The penguin shrugs. "Yeah. That's a ninja." the penguin replies. You laugh. "Don't be silly! Club Penguin doesn't have ninjas." you tell him. The penguin shakes his head. "You clearly haven't seen the shadows." he mutters. You look up, alarmed. "Shadows?" you ask, kind of scared. He nods. "I've seen them around the island." you whisper. The penguin nods again. "Those are ninjas." he answers as if it's the most obvious thing on Club Penguin Island. "Ninjas were really smart penguins. VERY. But then, a terrible disaster struck Club Penguin Island. Penguins believed it was because of the ninjas. The poor ninjas started to believe that too, that they were the cause of the disaster. Nobody knows, except some wise ninjas that really believed that they were not the cause. It's a very old legend, but I believe it's true. It might have not happened, but there are ninjas around the island. They are shadows, because they are well hidden." he smiles. You gasp.
"So those rumors about the penguin who digs the snow is true?" you demand, mystified. He laughs. "DUH. They couldn't find a suitable penguin to dig. They called a ninja. That's why he is smiling. He is laughing about some penguins... like you. Because of your lack of knowledge about ninjas." the penguin says wisely. You frown, shake your head and walk off. Later in the day, you find a book called: THE ART OF NINJAS. You grin. You start reading the book immediately. The book has the same information that penguin gave you, except in different words. "Why, this must be true!" you exclaim. And yes sir, it is.
