Outside: Poseidon's Cabin is a long, low building with windows facing the ocean, and looking like it's made of rough sea stone, with pieces of coral at the end of the cabin and a seashell and a trident over the door. There is always a sea breeze blowing through it.
Inside: walls made of abalone with rows of neat bunks, and a salt water fountain. There is also a sort of mobile of hippocampi.
