Story
Many months have passed since Zero One and Dr. Shinichiro have attempted to take over the islands, and it is now summer vacation. While Thunder was relaxing with nothing to do, Julie recommended someplace to go while the holiday is still around. She recommends a place known as the Miracle Kingdom, a kingdom located near the Petro Islands. Thunder invites Bay, Quinn, and Crugg while Julie introduces two new characters: Shelly and Soul Squareshell. When they arrived in the Miracle Kingdom, they were formally introduced to the ruler of the kingdom, Princess Quartz VI. But suddenly, the kingdom was attacked by a yellow dragon, so Thunder and the heroes go deal with it.

After the dragon was tamed, Quartz revealed that the eight gems of the kingdom, the Sacred Orbs, were stolen and those guarding them were taken away. Now with the help of Pyro, the dragon that was calmed as a result of losing his wings, Thunder and his partners must work together in order to reclaim the Sacred Orbs.
