Underwater Farting Penguin
The penguin in front farts and the one behind turns around desperately so he doesn't swim into the fart bubbles. It's like the smoke-screen in the old-shcool SpyHunter video game, except that i am nearly certain that penguin, in fact, sharted, so it's more of an oil-slick, or some sort semi-fluid deep-sea mine (the analogy is breaking down but you catch my drift).
