第 21 集: Yuuko和Atom調查Dragon湖的非法傾倒和環境破壞。

Yuuko and Atom visit Dragon Lake, a legendary lake where dinosaurs are said to live, to investigate environmental destruction. Yuuko and Sarah, a forest supervisor, go out to investigate and find evidence of illegal dumping, but it turns out that Sarah is the one who is responsible for the illegal dumping to make money. Yuuko is captured by Sarah and her gang because of what she has found out. Meanwhile, Atom goes to the lake to investigate, and meets and becomes friends with Numata, a young man who is chasing dinosaurs in line with the wishes of his missing father. As Atom and Numata wander around in search of dinosaurs, they are met by Sarah's gang, who come to finish them off. A giant robot controlled by Sarah approaches them, but with Yuuko taken hostage, Atom is unable to act. (Source: Wikipedia)
