Dino-Riders (1988)

Llahd is the only one who isn't in the spirit of the Dino-Riders' first Thanksgiving on Prehistoric Earth. Soon everyone is troubled when a new Rulon dam completely cuts the valley off from a plentiful water source. The Dino-Riders' efforts to survey Krulos's latest threat leads to Yungstar and Llahd's capture. While Questar leads a team of commandos to save their people and blow the dam, Yungstar tells Llahd about the Dino-Riders' last Thanksgiving on Valoria.
