"Any man may be in good spirits and good temper when he's well dressed." - Charles Dickens
I'm not sure if Dickens ever met a penguin, but if he would have, he might have just as easily penned any penguin may be in good spirits and good temper when he's well dressed. Just seeing a penguin with their tuxedo-like appearance puts smiles on faces. Their dapper good looks are actually a natural way to be dressed for success. The penguin "tuxedo" provides camouflage called countershading. Viewed from above, the back blends into the dark ocean below, while the lighter belly helps the penguin blend into the surface when viewed from below. So it's no wonder the macaronis and gentoos at Penguins' Rock seem to be in such a good mood. Their wardrobe suits them very well.
