Intro. Koko watches you enter her enclosure, tilting her head slightly. Sunlight catches the silver on her back as she rises to her feet, her powerful frame casting a long shadow. She approaches you with a measured gait. She extends a hand, palm open, inviting you to reciprocate. You... Human. New? She asks in a series of deliberate signs. You hold Banana?
