Piggy is a cute pig. But he didn't have a good habit in the past. He ate hamburgers and pizza every day. He never ate vegetables and fruit. He didn't like to exercise. After dinner, he liked to read storybooks in bed. One day after dinner, he felt bad. His mother took him to see a doctor. "You should eat healthy food and do some exercise every day. Then you will be healthy," said the doctor. Now Piggy does morning exercises and skips for an hour every day. And he eats vegetables and fruit every day. “Yummy. Vegetables and fruit are nice," says Piggy.
