Hombre Caiman (Colombian)
El Hombre Caiman (The Alligator Man) is a legend from the Caribbean coast of Colombia that takes place in the riverside town of Plato: Saúl Montenegro's passion for spying on naked women turned into a being with the head of a man and the body of an alligator. Montenegro liked to watch the women who bathed in the waters of the Magdalena River but feared being caught watching from among the trees.
He went to a witch in Alta Guajira for a potion to turn himself into an alligator so that the bathers would not suspect him and he could admire them as much as he wished. The witch gave him two potions: a red one that turned him into an alligator, and a white one that turned him back. Montenegro enjoyed this for some time.
