Valley of the Dinosaurs - Season 1 - Eps 1: Forbidden Fruit
The Butlers and Tana are gathering fruit that looks like an orange. Gorok and Lok come by and tell them to leave the fruit. It is reserved for a Brontosaurus. At that moment the Brontosaurus shows up hungry for the fruit. Everyone leaves the fruit except Greg. He sneaks it back with him to the cave. The Brontosaurus finishes all the fruit and even the leaves on the tree. He smells the fruit that Greg took and follows them back to their cave. The Brontosaurus causes a cave in while trying to get into the cave to get the last of the fruit. They are all trapped in the cave. The cave starts to fill with water from an underground river. Greg and Tana find a way out and scare the Brontosaurus away with a landslide of rocks. In the meantime, the others are siphoning the water out with a bamboo tube to buy some time. Greg drops a vine down through a hole in the ceiling and saves all of them.
