Captain Planet and the Planeteers (1990)

Episode Overview

While working on the Eco-Sub, Gi grew frustrated with Suchi and disregarded his advice to fit a new component into the turbines. As a result, they lost control of the sub's steering. This becomes a major issue when they pursue Sly Sludge, who is releasing toxic waste into an Asian sea. The pollution leads to alarming mutations in marine life, particularly a squid that expands dramatically and starts attacking people and eventually threatens a nearby city. The Planeteers must put an end to Sludge's illegal dumping and save the city from the monstrous creature.
