I think the theme of this movie is the importance of the coexistance with nature.
At the beginning if the movie, vermints lived peacefly with nature.
However, other vermints brought the industrialization, and they dastroyed the beautiful nature.
I think these kind of vermints are the symbol of the present people who desire the covenience.
Vermints suffered from the bad effect of industrialization, but they could not stop it.
Lastly, the jerryfish which represent the nature helped the varmints and purified the
industrializations. Vemints took back the beautiful nature in the body of jerryfish.
Wathing this movie, i really felt that we should find a way out of our destroying the nature, and
should consider the way to coexist with the nature peacefuly.
