This story begins in a halcyon greenland. The main character is a male creature which looks like a rabbit and a raccoon mixed up. One day, the nature gets destroyed by the buildings and factory smokes. he managed to take a branch at the last moment. As the air pollution gets worse, animals begin to die. In the end, the glowing seed which came out from the varmint's branch, saves him, the other animals and the nature.
This story is really inspiring. I think the director wanted to tell us that never give up. The nature is getting destroyed at this moment but is we keep trying to bring nature back to life, it will eventually succeed.
