Ningen hjóhon 5, 6 (E28)

A subterranean monster at the Otayama gold mines destroys the town of Muro. Captain Muramatsu launches the Vellucidar, a new drill-boring tank capable of tunneling underground. The SSSP are attacked by Goldon. They manage to drive it to the surface, where it is damaged by the Vellucidar's laser gun and SSSP weapons fire. Ultraman finally vanquishes a second Goldon monster with his Spacium Beam. (Prime Video)
