Humbaba is a big, scary monster from an old story called the Epic of Gilgamesh. He has sharp teeth, horns on his head, and a body covered in tough scales. He lives in a forest and guards it from anyone who might want to chop down the trees or take something from his home.
Imagine a big, mean dragon who would do anything to protect his treasure. That's kind of what Humbaba is like, except he's a monster who lives in a forest. He's the boss there and nobody messes with him.
But one day, a hero named Gilgamesh and his friend Enkidu decide they want to chop down some trees from Humbaba's forest. They know it's dangerous, but they're brave and want to prove themselves.
So they go to the forest and try to fight Humbaba. But he's too strong and scary for them, and they almost give up. However, with courage and quick thinking, they eventually defeat Humbaba and become famous heroes in their land.
So, in summary, Humbaba is a big, mean monster who guards a forest, and he was defeated by a heroic duo named Gilgamesh and Enkidu.
