Pierre, a 25 year-old Jackass penguin, was going bald. In addition to making him the laughing stock among his fellow penguins, it also left him unable to swim in the icy water. With no feathers to keep him warm, Pierre was left stranded, forced to watch longingly from the shore while all his penguin friends froliced and swam in ecstacy in water to fridgid for a featherless Pierre to go.
So, the zookeepers made him a wetsuit.
And if you don't think a penguin in a wetsuit is adorable, you're a heartless fiend.
