Summary
One day the city where the protagonist lives in undergoes a catastrophe. As a result, the once beautiful place utterly changed into a dark, dim and withered city. Before all the plants die out, the protagonist saved one branch and seeds from the tree he usually rests.
Later he discovers a glowing seemingly radioactive green bubble on the building. Soon, the bubbles in the city grow bigger and turn into gigantic hollow jellyfish roaming in the sky that capture other animals.
In the end, main character gets caught, and finds the inside of that jellyfish is the beautiful place just like the place he once lived.
Reaction
I think this short film is a reflection of the repercussion of industrialization. In the beginning, the transformation of the city is a representation of the rapidly changing city and the byproduct of it (environment change). The trees withered, the sky is covered with toxic gas, many animals got sick. The animals are the symbol for endangered animals. The green massive jellyfish represent the preservation organization human send out to save endangered animals. Each jellyfish is artificial habitat for rescued animals.
I think the video is meant to raise the awareness for the environmental damage we inflicted on other animals and how important beautiful nature is to wild life. When the whole city is changing, the main character rushed to save one branch of a tree and some seeds. This shows how much he wants to save his home.
