Terry is a blue, spherical penguin with black, beady eyes and an orange beak and flippers. He's a sarcastic, hot-headed, dismissive, complaintive and slightly cynical guide who provides instructions and advice, albeit begrudgingly. He's surprisingly knowledgeable and experienced in most elements of the game, but wary of strangers, often mocking and insulting them. He speaks mostly in street slang and has a rocket launcher. He used to be a professional pilot and has a younger brother named Jerry.
