What do koloa eat?

It seems like you're asking about the diet of a "koloa." However, there is no known animal or organism called "koloa."

It's possible you might be thinking of something else, like:

* Koloa, Hawaii: This is a town in Kauai, Hawaii, not a creature.

* A misspelling: Perhaps you meant a different name, such as "koala."

Could you please clarify your question?

If you can provide more information, I can help you find the answer!
