All the koala-roos hopped hight and hung from tree branches for sport. They played games. They had contests. All except Cally. Cally sat sadly and watched. He wished he could hop hight enough to be able to hang from the highest branches. But poor Cally wouldn's even try. He was sure he wouldn't make it. At frist his friends tried to convince him to do it. "Cally , come on. You can do it!" they yelled.
