It's a good question, isn't it? Penguins waddle about on ice, but their feet don't freeze. The cover of the book suggests that this is because of a pair of stripy socks and some snow boots, but the truth is more prosaic. Penguins are able to control the flow of blood to their feet. In cold weather the flow is reduced and the temperature of the feet is held just a degree or two above freezing to prevent frost bite and reduce heat loss.
