Well, for a penguin, it doesn't take much to bundle up for a snowstorm. But even a mother penguin is known to nudge her child to wear a hat!
While you can create a variety of penguin characters, there is one caveat: Penguins have to be cute! Even if you're drawing evil penguins, they have to be cute-evil. It's a rule. If you break it, you'll get hate mail from penguin lovers all over the world.
Here's an important hint that is sure to make them look cute: Penguins have almost no legs! Their bodies are basically plopped down on their large flat feet. They're all tummy! This gives them a stubby, adorable look, even though they've got a long torso, because the torso is always abruptly cut off at the feet.
