Dungeon Objective

 * This dungeon has a wide variety of Pokémon and most of them are Water and Psychic-type, which is good for training Pokémon with types that are super effective on them.
 * The dungeon's floors usually have small amount of rooms, while Pokémon tend to spawn a lot and give out good amount of experience. Consequently, it's a good place to train Pokémon.
 * This is the only place where players can recruit Gothita. Also, Munna, which used to be available only in HC, is now recruitable here.
 * Players can also obtain Jirachi's Heart Slate (rare chance) and use it with the Mystery Part to summon Jirachi in dungeon. This also gives players access to its signature move, Doom Desire.

Trivia

 * This dungeon is made completely by kittu.
