The Scylla is a sea creature that is a nymph waist up which goes under water when it attacks with its six
enormous wolf heads waist down. It was orignally a girl that was raised by wolfs and was trying to follow a man who promised love and riches of her imagination but the man was just using her to kill a man. Then she drowned trying to swim aboard the man's boat but, when she drowned Poseidon changed her into a nymph but instead she turned into a half nymph half deadly 6 headed wolf beast.
