[ku-] Koopa Troopa is in [1] front of the [-_] house building his own little 窟 den. He digs a large crevice, making two 山 mountains on each side, then makes a roof by connecting a bunch of walking dollhouses by the legs, forming his dark 窟 den on the lawn. He puts a 尸 flag in front that says: "Koopa's 窟 Den".
