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 Happy Home Designer, he is a normal staff member at Nook's Homes. His job is to help the player with rebuilding facilities they have already built. This feature is unlocked 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.
Digby has a relaxed personality much like his sister, Isabelle. He is patient and very straight-forward, although he sometimes feels concerned about his job being the gate guard of the Happy Home Showcase area. He also gets along with his sister Isabelle, as she does also.
Digby is mostly brown in coloration. He wears a white shirt under his red suit coat, accompanied with a yellow tie and blue pants. On rainy or snowy days, he will wear a yellow raincoat and red boots. He resembles Isabelle in his features; he has the same eyes, but his white patch is seen running up the middle of his face and he has a tuft of hair sticking out on the top of his head. He also has six pink freckles, with three on each cheek.
In New Leaf
In New Leaf, he stands on Main Street outside the Happy Home Academy. When it's rainy, he wears his yellow raincoat. The player may talk to him, which grants access to the Happy Home Showcase, in which they can visit the homes of other players using the Nintendo 3DS's StreetPass feature.
In Happy Home Designer
Digby also appears in Happy Home Designer, where he plays as the player's co-worker. Digby's job is to work with all of the paperwork related to new facility buildings that are added to the town, and they will usually see him at the end of the day finishing up some of his work. He doesn't interact with the player much, though he is an important character. After designing enough facilities, Digby will give the player the option to rebuild any facilities that they already have, and takes over instead of Isabelle during remodeling days.
