What type of foods do hangolla eat?

There seems to be a misunderstanding. "Hangolla" is not a recognized food source or animal. It's possible you've misspelled a word or are referring to something else entirely.

Could you please clarify:

* Are you asking about a specific type of food? If so, could you provide more information or spell it correctly?

* Are you asking about what a specific animal eats? If so, please tell me the name of the animal.

Once I have a better understanding of what you're asking, I can help you find the answer.
