This story takes place where there is nothing except for nature. The main character of the story is a rat look-alike creature(male perhaps). One day, all of the sudden, many other rat look-alike creatures were dragging buildings and factories to the place where the male was living happily. Somehow he manages to save a tree branch to look after. With all the pollution from the factories, everyone becomes sick but one day, a jellyfish-like creatures comes to gather all the people in the city to rescue them. They end up in a place where everything was normal, where before the buildings and factories were brought. The main character was even able to meet his destined partner again. This film teaches us how the future might look like if we do not conserve our resources.
