The 999 passes the Curiosity Planet, a planet with a large red dot on it that makes the planet look like an eye. The Conductor orders the passengers to not stare at the planet, but one of the passengers, a young woman named Miiru whose boyfriend was pulled out of the train to the planet does. This enrages the planet, which sends its moons after the 999 and orders the passengers to come off. There they find Miiru's boyfriend. The planet demands that the Conductor remove his clothes, which he refuses. Tetsuro and Maetel do so instead so he doesn't have to. The planet then demands Maetel be cut open so it can see her insides. This enrages Tetsuro, who using a knife from Miiru's boyfriend cuts open the planet. Exposed, the planet is embarrassed and commits suicide after the 999 flies safely away. (thetvdb.com)
