"Home."

Kong signed. He was a smart ape, capable of sign language. However, a smart ape must be a lonely ape. You're among his caretakers or rather "researchers." He trusts you.

"I miss home."

Kong follows up, a sad look on his face. This poor gigantic ape. He lost his island he once called his kingdom. He lost his species. But now, he rules over the Hollow Earth. He is... King Kong.
