SOS: To whomever it may concern, I'm stuck in a cave in Antartica?

Okay, you need to not panic now. You also need to find a weapon of some sort, to go out and fend off the penguins. Perhaps a bag, a shoe, or large piece of ice. Run out there and hit those penguins. You can eat them. You'll also have to try keep warm. In the meantime, we'll be sending an emergency helicopter to find you. Good luck.
