The season introduces new dinosaur characters, including Spinosaurus, who is almost as big as the title character, and the Incisivosaurus Missy, the maze guardian. An array of musical sequences accompanies the dinosaur frolic. 

Season two, which premiered on Disney Junior in January, debuts on Disney Plus Aug. 25.
