There are no classrooms in Animal School, but there is a forest and a river. The forest is not small. It's big and green. The river is small, but it's long. Look, there are some animals there. Listen, what are they talking?
Mr Cow: Welcome to Animal School What's the matter?
Little Duck: I'm sad. I can't run, and I can't jump. I'm a bad duck.
Mr Cow: I don't think so. Please don't be sad.
Animals: Come on, everyone! Let's swim together!
Mr Cow: Have a try, Little Duck! You can swim very well.
Animals: Wow! Look at the Little Duck! He is so fast!
Little Duck: I'm the first! I'm so happy!
