summery: There is an animal in the field. Suddenly, the city is built rapidly and nature got broken. At the city, people are very dirty and seem to be hopeless. People die everyday because of air pollution. One day, big creatures shaped like jelly fish appear. They catches people. Main character get caught, too.
my opinion: I think the theme of this animation is environmental protection.
This animation is suggesting our current society.We will destroy nature like this animation unless we do something to protect them.
