Digby is a dog who is in charge of the Happy Home Showcase in New Leaf, and is the twin brother of Isabelle. He can be seen standing at the Showcase's entrance all day long.

In order to get into the Showcase, the player must first speak with him. Once inside, the player may visit the houses of other players they have met through StreetPass.

In Animal Crossing: Happy Home Designer, he is a normal staff member at Nook's Homes and can help you with rebuilding facilities you have already built. You unlock this feature after upgrading the school with Isabelle.

In Pocket Camp, he returns to work at the Happy Home Academy, but instead of being the gatekeeper of the Happy Home Showcase, he is one of the Happy Homeroom Judges.
