While on a fossil hunt, the DTeam hears someone or something moving huge boulders underground. Moving in to investigate, they spot the Alpha Gang, who are using their dinosaurs to excavate large pockets of Alpha Metal needed to repair the failing machinery that powers their base. Guessing their archenemies are up to no good, the DTeam tries to put a stop to their mining operations, but no sooner do they enter the mines than do they encounter a Futabasaurus, a prize catch that is certain to attract the attention of the Alpha Gang.
