Once upon a time there was a hideous crocodile and his name was Mr.Big . He lived in a sewer. Everyday , somehow mice always came down the drainpipe , and Mr.Big always ate them without hesitation . But one gloomy day a frog came instead  of mice. Mr.Big thought why it came down the drainpipe, and why was it a scrawny frog and not mice?Mr.Big slithered to the frog …….it was pale . Suddenly the frog woke up and jumped on Mr.Big. Mr.Big was so frightened, he fell into the water, never to be seen again!
