| Mr. Gruber
| Character Information
He is a bald eagle dressed in a standard mailman uniform with a gold belt to go along with it.
- Mr. Gruber is very likely to be based on the character Simon Gruber from the movie Die Hard with a Vengeance, due to his similar voice and motivations. He also mentions a brother named Hans, presumably a reference to the aforementioned character's brother from Die Hard.
