Penguin cartoons. Penguins that are all different colours – because black is no longer fashionable (for penguins)
A cartoon showing multicoloured penguins.
The joke is that penguins are all black, which happens to be a fashionable colour in some areas of human fashion. Penguins are often thought of as wearing dinner jackets, so in this cartoon I’ve given drawn brightly coloured penguins as though they can change their colours to suit fashion.
