Inferno

S3 E3: Ben, Kevin, and Gwen look into a disturbance that has brought Pyroxivores to the surface from the underground. During their search, they meet a riley creature named Mouldywarp who is angry at a "claim jumper" that has moved in on his ground and is scaring his Pyroxivores. They soon discover that Vulkanus is causing the disturbances with his plans to drill to the center of the Earth and turn it into a molten world of lava like home sweet home.
