The Flower Key House is a red house located in Ant Kingdom City's main plaza. It can be unlocked using the Flower Key purchased from Beette.

Inside the house is a bed that can be used to heal Team Snakemouth for free. There is also a bed for Chompy allowing her to be left behind or have her ribbon changed.
