Pingu

Pingu is the main character in the series of the same name. 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.
