Some people mistake him for a husky dog instead of a wolf, due to the fact that a husky dog also has a white underbelly.
He pronounces penguins as peng-wings, similar to his voice actor.
He dislikes anyone referring to him as "Classified", and often highlights that it is not his real name, despite the fact that he does not have another known alias.
Despite the nature of his name, he is still referred to as "Classified" in the credits, without quotation marks around the name.
Classified was one of Benedict Cumberbatch's First Major Roles Post-Sherlock and Pre-Doctor Strange. It was a Major Role for Sir Cumberbatch as he actually includes a photo on his resume that shows him and Skipper.
