Volcanic Giant Slugs

From Mylegokingdom

Volcanic Giant Slugs are ugly massess of molten looking flesh. They crawl along the Molten Plain and feed on valuable minerals there, which is why it is impossible to even mine there. Their blood is the equivelant as lava, and as a defense, it has a constant wound on the top of its back that sprays out "lava". They recover from the blood loss by constantly creating new blood from whatever they eat.
