This is quite a bizzare creature to us. It breathes the toxic fumes of vulcanoes, actually extracting some of the chemicals that it uses for nutriance. Some of the chemicals are also used for selfdefence too. Very litte is known about the koffing, but its lack of biting teeth or claws suggests that it at least isn't carnivore. It is quite possible it lives off the the chemicals that gathers in volcanic pools of water. The toxic fumes from our industrial plants has been attracting some of these beings to our civilization. Some are used like watchdogs in plants where there are areas were humans need environment suits to patrol.
