Digger is a main character in the Guardians of Ga'Hoole book series and its film adaptation, Legend of the Guardians The Owls of Ga'Hoole.
Digger is light-hearted, kind, heroic, and quite the jokester.
While having a punch line thrown in, Digger considers his jokes to "be a hoot". However, Twilight finds them annoying. His jokes normally don't make sense. For example, he asks Soren and Gylfie for this type of joke:
"Do you know what they call owls that fly towards the sea? Lost!"
Both of them just looked confused at each other without even a chuckle. The second time (onscreen) was his last joke of the night when he tells them a knock-knock joke about owls saying "who" after Gylfie responds to his joke, much to Twilight's annoyance. Digger is a soul with a good heart, for he allowed Soren and Gylfie to stay in his and Twilight's hollow after learning the female owl was injured on their flight and sympathetically smiles at her.
However, despite all of his jokes, Digger is sometimes serious, such as fighting for his life
