III Poseiden

Cabin III, Poseiden's cabin. A long, low building with windows facing the ocean, and looking like it's made of rough seastone, with pieces of coral at the end of the cabin and a seashell and a trident over the door. Percy described its smell to be same as the cabin at Montauk where his mother and father met. Inside: walls made of abalone with rows of neat bunks, and a salt water fountain (it was replaced after Percy destroyed it). There is also a sort of mobile of hippocampi.
