Pyroxovore

Pyroxivors are a type of subterranean cattle that eat rocks. They are native to Earth.

The Pyroxivors were first shown on the show in Episode 3 of Season 3 of Alien Force, "Inferno." In this episode, the Pyroxivors were driven up by the earth growing wamer, because Vulcanus was drilling a hole to the Earth's Core, as he was the rightful owner of the Earth. The Pyroxivors returned to the ground when Vulcanus was defeated.
