Ep 15. Volcanic Panic

Max and Rex are on their way to the Hot Springs when they discover a strange Portal. They go through it to find themselves in the dinosaur era where a Volcano is about to erupt. Max and Rex meet Terry, a Pteranodon dinosaur. Terry tells them about the Volcano and how it will destroy the whole area. Max and Rex see a Tarbosaurus and fight with it in order to protect Terry.

Meanwhile, Dr. Z wants to capture Terry because he is a rare breed. Dr. Z and his team find out about the Volcano and decide to use it as their chance to capture Terry. Zoe and her dad Tom are also on their way to the Hot Springs and they run into the Alpha Gang who tells them about the Volcano.

Max, Rex, and Terry reach the Volcano only to find that the Alpha Gang and Dr. Z have already arrived there. The Alpha Gang tells them that they are there to help, but Max and Rex know better. They engage in a fierce battle with the Alpha Gang and Dr. Z's team. They manage to save Terry from being captured, but the Volcano erupts and they are all trapped.

The group decides to work together to find a way out of the Volcano. They find a small hole in the wall and decide to crawl through it. They reach a tunnel which leads them out of the Volcano.

In the end, Max and Rex say goodbye to Terry and go back through the Portal to the present day. They are relieved to be back home safe and sound. They realize how lucky they were to have the chance to visit the dinosaur era and hope to have more adventures in the future.
