Encantado: Although they don’t look so scary when appearing in their human form many South Americans are so terrified by this Brazilian mythical creature villagers will dare not go near the Amazon River at night because that is where the creature roams in its human form – its most dangerous state. By day the Encantado lives as either a freshwater dolphin or sea snake. When they transform into humans though they behold superior musical abilities, seductiveness, and attraction to parties. Their victims can be driven to insanity, illness or even death. (Source:
