Poseidon's Cabin

Poseidon's cabin (#3) is low, long and solid, with all the windows facing the sea. The outer walls are rough gray stone with pieces of seashell and coral and look like the bottom of the ocean floor. On the inside it has six empty bunk beds and the walls glow like abalone.

Later in the series, Poseidon adds a fountain for his sons (Tyson and Percy Jackson). The fountain is made out of gray sea rock, has a fish that spouts the water from its mouth, and has a coral decoration. The bottom is filled with gold drachmas for Iris messages, although it is unknown that if the coins will ever run out. Tyson later adds a few bronze Hippocampi on the ceiling as decorations. He also added unknown underwater plants and corals, sitting in the window sill, "more beautiful than the Demeter kids could whip up," Percy commented.

Known occupants

 * Percy Jackson (Counselor)
 * Tyson (when he visits)

Legacy Powers
Some legacies of Poseidon have different powers. They cannot do any of the above powers, but, if a legacy of Poseidon is from the line from Periclymenus, then they have the ability to shapeshift into animals.

Magic Items

 * Percy has a magical celestial bronze sword called Anaklusmos or Riptide.
 * Percy had a magic wrist watch that transforms into a shield. It was given to him by Tyson in the disguise of a watch at the end of The Sea of Monsters made by Tyson. It was lost during the Battle of the Labyrinth.
 * Percy has a Minotaur's Horn which he ripped off its head while fighting the Minotaur in front of Half-Blood Hill (in the movie the horn breaks off and sticks to a tree from where it is taken by Percy and is used to kill the Minotaur) in The Lightning Thief the movie. The only entrance to Camp Half-Blood in The Lightning Thief book and film is by passing the invisble barrier around the small hill.
 * A Saltwater Fountain was provided by Poseidon for his children in the Poseidon Cabin in The Titan's Curse, until Percy destroyed it in The Battle of the Labyrinth being scared of what he was hearing and seeing (about Nico).

The Lightning Thief
Although not said to be the cabin, Percy stays in an open cabin by the beach built by his father, Poseidon. Chiron stated that Poseidon built it just for Percy, although he might have just meant all of his children, though he had no other demigod children. In the cabin, there was a life sized trident, and many other helpful objects that Percy could use. The cabin gave an excellent view of the ocean.

Trivia

 * Poseidon's cabin is tied with Zeus' cabin for having the third least amount of possible inhabitants, the first being Hera's cabin with no inhabitants.
