Ep. 40: Goku and Eighter battle the indestructible monster Buyon on the fifth floor.

Goku and Eighter arrive on the fifth floor, where General White unleashes the monster Buyon to eliminate them. While Snow discovers sweet furry rodents, Eighter hides in fear as Goku engages Buyon. The monster proves immune to physical damage and consumes Goku, who manages to escape. A Kamehameha Wave fails to harm Buyon, but Goku recalls a previous interaction with Snow. He punches a hole in the wall, allowing cold air to enter and freeze Buyon solid. Goku then shatters the frozen creature, rescuing Eighter from being eaten. Together, they ascend back to the command room, having defeated the threat.
