Ultraman: S1 E35 - The Monster Graveyard Ultraman

Ide and Arashi discover the monster graveyard while patrolling the Ultra Zone of the Universe. They pray for the monsters beaten in the past, but just then the Japanese first moon rocket hitched the monster Seabozu which was drifting in the monster graveyard and dropped it to the earth. In order to return Seaboze to the monster graveyard, SSSP plans to launch it on a rocket.
