Once upon a time, in a sunny pond, there is a happy duck. She swims and plays all day. One day, she meets a strange animal. It has a bill like a duck but feet like a beaver. "Who are you?" asks the duck. "I am a platypus," says the animal. The duck is surprised. She never sees a platypus before. They become good friends. Every day, they swim together. They have fun and share food. The duck learns that being different is good. The platypus is happy to have a new friend. And they live happily in the pond. The end.
