Dear lord they are cute! But as cute as they are, these sweaters are functional as well. Seems that penguins who have had unfortunate run-ins with oil spills are put in these little sweaters after they have been cleaned up. The oil destroys their feathers as well as the oils in their skin that help keep them warm and cozy and clean and healthy. So the penguins (in this case off the coast of Australia) are given the sweaters during their time in rehab while they regain their strength and heal so they can be released back into their habitats.
