[ku-] Koopa is in the [4] bathroom of the [-_] house, which is the entrance to his special 库 warehouse. He rubs his shell against a special part of the bathroom tile wall, and it opens into a huge space. There is a small 广 shack that Koopa sometimes sleeps in, and next to it a 车 car, that got stuck in the 库 warehouse and can't get out because the only way out is through this bathroom entrance. Wait, how did these things even get in, then?
