Pyroclasmic Slooch

This creature comes in play tapped
"A species of terrestrial snail coated in flammable
mucus instead of the traditional shell. The creature
stays lubricated through constant secretion of mucus
so that the fires never reach its skin. The most
fascinating aspect of these creatures is their
instinctive ability to avoid causing widespread
fires by carelessly brushing plants."- Captain Olimar
