Sophocles tells a campfire story about a legendary starship. He eventually discovers that the legend was not quite as fictional as he believed, and it brings the Ultra Guardians back to action.
This episode contains examples of the following tropes:
- Expy: The legend of the Celestial Starship is very loosely based on the Japanese legend, The Tale of the Bamboo Cutter.
- Story Within a Story: The legend of the Celestial Starship, which landed in a bamboo grove and drained its energy. But when it launched back to the Moon, it left a rejuvenated bamboo grove.
