They were celebrating the recovery of Uncle Frank at the Giant Fortress, and saw the news that the nearby residents were impeded. On the site, regardless of the mass protests, the foreman led the workers to carry out construction, and Rock Turtle Beast appeared and destroyed the site. Being informed of this, Don ordered the guards to investigate, but Benjamin stopped the mechanic warriors from investigating this case to prevent injuries. Don insisted on using them and took the responsibility himself. All the guards arrived at the site and were to blow the Rock Turtle Beast, but they were prevented by Gandi. Gandi was told that Rock Turtle Beast was a good man, and asked Quinn to promise not to injure Rock Turtle Beast. When Commander Ming was resurrected, he learned from Miss Kyi and Silver-carp-head that the Giant Saver and the Assault Saver have been used by human beings, the commander saw that Rock Turtle Beast actually was one of the twelve mechanic warriors, so he ordered the two beasts to bring it under control. Quinn reported the investigation results back to the base, and they were all confused about if the Rock Turtle Beast was on their side or not. Rock Turtle Beast was making destruction in the quarry, so Earth Guardwanted to kill him but was blocked by Gandi. The five guards arrived at the site, fought against the Earth Guard were defeated.
