Pingu

His name comes from the German word for penguin (Pinguin). His original name was Hugo when he premiered in a short created by Otmar Gutmann in 1984. His full name is unkown, however, he has had many fanmade full names, a popular one being "Pingu J. Penguin". The J has been said to be Jeffery, but the fact that Pingu the show is from Switzerland makes this unlikely.
