Frog is taken by surprise when winter comes. He doesn't understand why everything is covered with white and he skids and slips on the icy pond. He is too cold to take part in any of the joyous fun that Duck is having skating or that Hare is having throwing snowballs. The animals band together to equip Frog for enjoying winter, and later they share in his rejoicing when spring arrives. "Frog is an inspired creation - a masterpiece of graphic simplicity." (Guardian).
