As photos show, the horses couldn't have been happier with their regal-looking guest.
Sarah Croft, an officer from Falklands Conservation, told The Dodo that she had just finished feeding the herd when their ears suddenly perked up as the penguin approached.
"He caught all of their attention. From afar, the horses were just curious, but then the penguin got closer and some of the horses came in for a closer look," she said. "They've never seen a King penguin before, so I think they were quite fascinated with what it was."
