Hyena of Hunger is an enemy in BLACKSOULS that can be found in the Behemoth Ranch, to be specific, in the upper area of the ranch that leads to Jacob’s Disused Mine.
As soon as you enter the fog, he will rush straight towards you, rushing to kill you, but luckily enough he’s not difficult to defeat even if you’re at the start of the game. After you take a significant portion of his health, he enters his furious phase where he’s more aggressive and madder.
Once you defeat him, you will not get a lot of souls, but if you continue further you can find the Three Little Pigs fairytale.
