Pyroxovores are considered to be a source of food.
The Pyroxovores were driven up from below the Earth because Vulkanus made the Earth warmer by bringing up heat from the planet's core, as he was the rightful owner of the Earth after buying it. The Pyroxovores returned to the ground when Vulkanus was defeated.
