Well, as said before, you want to go home because it's getting quite late, and your kind of excited to talk with your friends.
In the kitchen/dining room/living room, the level you're currently on, you finish up that fish that you were eating, and find a ladder to the room below.
This is the room your sister puts all her frogs, beit knitted, like the one still in your modus, or plushies, like the dragons from your catfriend's house, or any other physical malibut. You don't really mind this room, as its floor is somehow softer than your bed, but you don't like that this room's the stockpile for your sister's biggest fetish.
