The Three Heroes' Adventure

To keep the little carp from being polluted by black water, the little gray mouse sets off with the big orange cat and the short cabbage to find the source of the wastewater.

The three little environmental guardians pass through Scream-and-Celebrate Valley, defeat the villains ruling Twilight City, come up with a plan for Big Brother Bear, who can't hibernate, cross Plastic Mountain, and rescue the people of Storm City... At last, they defeat the waterborne green monster, water hyacinth, at the wastewater treatment plant.

Their journey teaches them about all kinds of pollution and helps them understand that Earth is our shared home. Protecting the environment is everyone's responsibility.
