In order to help the little carp not be polluted by the black water, the little squirrel, together with the big orange cat and the dwarf cabbage, embarked on a journey to find the source of the sewage.
The three environmental guards traveled through the Valley of Screaming Carnival, defeated the Twilight City ruled by evil people, gave advice to Brother Bear who could not hibernate, crossed the plastic mountain, and saved the people of Storm City... And finally defeated the water green monster-Eichhornia hyacinth in the sewage plant.
This experience made them understand many types of pollution, and also made them understand that the earth is our common home and it is our duty to protect the environment.
Purpose: Protecting the environment is everyone's responsibility
