Suss and Tina return to Hexagon Island for a third season of short episodes. The twin ninjas, whose family has guarded the island for generations, team up again with the AI robot Bull to face the SDG monsters that keep appearing one after another. Rather than relying on force alone, they fight with their wits and their words, drawing on wisdom gathered from around the world in their effort to save the Earth. Across 13 episodes, the action is played for comedy.
