Tokyo on the Hunt for Escaped Penguin

It sounds like the premise of a Disney movie, and hopefully it will have a happy ending: Aquarium officials are searching for a penguin who fled from the Tokyo Sea Life Park and was last seen swimming "at a tremendous speed" in a river headed toward Tokyo Bay. The one-year-old Humboldt penguin apparently scaled a wall in its escape, the BBC reports. Officials didn't know he was missing until a nearby zoo emailed a picture of the penguin yesterday.
