Loved the music first of all...
Anyways, this video clip really made me think hard on it. The conflict is the varmints v.s. the city. The city stands for artificial technology that pollutes/destroys the environment and the varmints stands for those who try to protect the environment. The jellyfish like object, I'm not sure what they were, stand for some sort of punishment to the people who weren't taking care of the environment. At the end, the jellyfishes took away the varmints from the city and they were all vital and happy again.
