Kookoo Kookaburra

Refusing to listen to the sage advice of his uncle, Kookoo gradually alienates all his friends until he finds himself alone and ignored by the other animals. When he finally listens to the sounds of his own laughter echoing around the bush and realises it has become an unhappy sound, Kookoo is forced to remember his uncle’s words and change his ways — kindness is like a boomerang — if you
throw it often, it comes back often.
