Orville is a dodo with blue feathers. He has a large yellow beak, with a brown tip.
Orville's outfit consists of a pilot's uniform. He has a white shirt with a red tie. Also, he wears a black belt, with a small pouch attached to it. He wears a black headset, in order to communicate with Wilbur.
The player can speak with him to set up a Nook Miles island tour, to open the town gates, to visit other towns either via local wireless or the internet, to visit Harv's island, or to participate in a special event activity (for example, May Day).
He also replaces Pelly and Phyllis, as the airport replaces the Post Office. By interacting with the Post Card display to the left of Orville (the player's right), the player can send post cards to villagers or other players (including other players of the same island).
