This film was about a creature that looks like a kangaroo and his struggle to preserve nature. One day he was living a happy life in a place filled with green grass and trees. However, a group of other creature comes and destroys the nature by building tall towers and factories. The creature managed to save a tree branch and he starts to take care of it. One night the tree branch makes bubbles from its leaves and those bubbles eventually grows into a jellyfish-kind of sanctuary. As the pollution gets worse and worse the creatures get sick and sick. Therefore, they need a new place to live in so they escape into the jellyfishes.
The main theme of this story is that if you don't care about environmental issues, our future will be doomed.
