Phantom of the Cave

This is the seventh episode of the series. After damaging water lillies, the kids hear a tale of dinosaurs that settled the Green Meadow and later disappeared. Crusty said that they might be able to find out answers to the mystery by going to the Cave of Spirits. They enter the cave, which looks scary on the outside and inside, and when they enter, there is an earthquake. The earthquake sends them sliding down a tunnel and into a room of skeletons.

Amber says that this is the Cave of the Old Thundermakers from Crusty's story. They keep hearing a voice telling them to "Leave My Cave!". Eventually, after some mishaps, they find the source of the voice to be a dinosaur with his head stuck in a log to amplify his voice. The dinosaur is an old Thundermaker named Red who takes care of the cave.

He said that they didn't take care of their habitat and that the place went bad, forcing many to leave. However, in the time since then, Green Meadow has recovered. They soon find scavenger raptors chewing on old dinosaur bones. Red says that they come there sometimes, looking for food. Red, along with the kids, help scare off the raptors.

As the kids say goodbye to Red at sunrise, he vanishes into thin air, revealing that he is in fact a ghost.
