She’s on her way to visit King Cryolophosaurus down in the Jurassic Antarctic and invites our family along.

King and Crystal’s heartfelt reunion is marred when Crystal tries to convince a reluctant King to take this fantastic new song out on the road to share with his adoring Mesozoic fans. But King doesn’t like leaving home and excuses himself to do some thinking. Buddy and Tiny follow and King sings a song called Good ol’ Gondwana to explain his feelings about his home. Tiny has a great idea—King and Crystal can perform a live concert in Gondwana and invite dinosaurs from around the Mesozoic to attend! The concert is a huge success, and King is surprised and delighted when Crystal decides to stay there with him instead of going back out on the road.
