You're exploring the Antarctic coastline as part of a study on emperor penguins when you see something large and dark in the water, moving at high speeds.

It's definitely a penguin, but it's way bigger than an emperor, and most men for that matter! It comes closer to the surface before finally leaping out and onto the icy shore.

It stands there, looking around and at you before letting out a loud honk, its beak skewered with the meat of a leopard seal.
