El Silbón

El Silbón or The Whistler as he is called when his name is translated is a violent Spirit from Venezuelan & Colombian legends. In most tellings of his story, he is stated to have been a simple farmer before becoming the infamous spirit he is now, after having killed his father. The legend of El Silbón begins with a spoiled brat of a boy whose parents catered to his every wish. One day, the boy demanded his father hunt a deer for him so he could eat his favorite meat. The father tried but could not find a deer and returned empty-handed. The boy killed his father, cut out his heart and liver, had his mother (unaware) cook them, and then ate them.
