Magmatuna is a cursed mutation of the freshwater tuna, resulting in a scalding hot internal temperature that is immediately devastating to any aquatic ecosystem. Their molten skin causes rapid evaporation of entire lakes and rivers, completely obliterating the ecosystem and resulting in nothing but burn marks and leagues of dead fish in a dry basin. The sighting of any smoke or mass-evaporation in a body of water should be immediately reported to the nearest government body.
