Ferocio is a sweet dragon who is challenged by scientist Geraldine Brain about his real identity. For this reason, he decides to travel to the center of the earth to prove that he really is a dragon. He travels for 90 days and 90 nights and when he arrives, he is pleasantly surprised. He would never have imagined that his parents were chained in a cave in the center of the earth. The monster of darkness had stolen the egg that was the fruit of the love between his parents and thus separated them forever and the powers of the dragons would be lost. When Ferocio finds his parents all of them recover the powers and Ferocio is never alone again.
