This video of a penguin named Tim who could easily be called Happy Foot, will make you smile and, I hope, instill some hope into what are all too often dismal days for nonhuman animals. It reminded me of the wonderful story of Molly, a horse who was fit was a prosthetic leg (see also) after she got injured after her owners abandoned her when Katrina hit Louisiana.
I want to emphasize that my posting this video is in no way in support of keeping penguins or other animals in zoos or aquariums, but if they're going to be there they must get the very best treatment we can offer them. They're not objects to be used for entertainment and then disposed of when they get too "burdensome". Lucky Tim and lucky Molly.
