The DONUT HOUSE is where a family of four sentient DONUTS reside. Its interior mainly consists of various breads and donut aesthetics. There are only a few interesting things for the player to discover. It is implied that the duchess SWEETHEART was raised there before moving to the wilderness of PYREFLY FOREST.
Interacting with the DONUT GRANDMA near the sink reveals that SWEETHEART is her granddaughter who originally lived within ORANGE OASIS. It is also revealed that SWEETHEART rarely visits this place but occasionally sends the DONUT family a postcard of how she's doing now and then. Interacting with the bookshelf will reveal a photo of SWEETHEART and SPROUT MOLE MIKE.
