The team finds dinosaurs which look like instruments. They see a mother Piccolodactyl together with her baby, but they hear a very forte sound coming from a Bassasaurus rex (or B-rex for short), and the sound is so loud and scary, the baby Piccolodactyl flies far away and hides in a log. However, he is unaware that he is hiding near a volcano, so it is up to the team to bring Baby Piccolodactyl back to his mother before the volcano erupts.
