The Toy-Con House is one of the five toy-cons included in the Variety Kit and was announced in First Look at the Nintendo Labo. The Nintendo Switch's screen is placed in the front of the house with a Joy-Con attached to the top of the house. There is a spring on the bottom of the house and a lever on the left side of the house.
"Toy-Con House: By inserting various assembled blocks into openings in the sides and bottom of the House, you can interact with, play games with and feed a cute creature on the front-facing Nintendo Switch screen. Each differently shaped block is detected by the IR Motion Camera on the Right Joy-Con inserted on top of the House."
