Godzilla: The Series - Season 2 - Eps 12: Shafted
While conducting another creature investigation in the valley of Blind Rock, Wyoming, H.E.A.T. meets up with a girl whose brother went missing after he entered an abandoned mine in the area where the sightings took place. Upon entering the mine themselves, the group discovers one of the strangest mutations they have yet encountered, a huge two-headed kaiju known as the Silver Hydra, on account of the fact that it has the ability to spurt a silvery fluid that hardens once it surrounds a living being, thus transforming them into the equivalent of a silver statue, a fate that obviously befell the girl's brother.
