Aromaswine

Native to the alien forests of the planet Faria, in the wild they are actually very foul scented. They are not very active creatures and they can be found in clusters with a noxious fog surrounding them protecting them from predators. It wasn't until recently that it was discovered that their scent clouds are based on the fruits they feed on, in some cases they can produce a rather toxic cloud. If fed sweet smelling fruits such as strawberries and oranges they will produce a very aromatic scent. Some believe that they still produce toxic vapours regardless what they are fed, even though after several years of domestication there appears to be no negative effects to humans. As long as they are not fed their native fruits that is. In fact some cases of humans with some respiratory diseases have shown an improvement in their symptoms after adopting this creature. It breathes through the slits on it's sides and it's lungs actually filter out contaminants and allergens in the air.
