Bikini Ghouls are found on the beaches of underground seas, lunging in suplurous lagoons and swimming in warm, piranha invested rivers.
With their faces concealed and in dim light, their curvacious form may fool an adventurer a long way from the warm embrance of the desired sex. Though they do not speak, the may emmit an Aura of Seduction that requires a great willpower to overcome.
If some unfortunate soul falls under their power, they will drag him or her below the waters and drown them, feasting like sharks upon their still living flesh. They are not warriors however, and will quickly scatter or flee once they have their dinner, or are outnumbered.
