Chapter 1: Ship Crash

Team RWBY and the Frozen heroes are transported to a place called Dinotopia, a place where humans and dinosaurs co-exist with each other. Even though there is peace, some strange creatures appear on the island, and they have even the mighty Tyrannosaurus Rex scared. Known as Grimm by Team RWBY, they must team up with the former residents of Arendelle and stop the Grimm from destroying all of Dinotopia.
