This releases a seal which causes the Bahamut to appear just as the dungeon plunges into the ocean.

Chocobo is rescued by a young white mage, Shiroma, who is the only human living in the monster village.

Chocobo must help Mog, find Bahamut and fix whatever has been unsealed from the Mysterious Dungeon.

Chocobo's Dungeon 2 is an action RPG in the style of other games in the Mysterious Dungeon series.

Chocobo must descend into dungeon areas alone or with a partner (controlled by artificial intelligence or the second player), gathering treasure, while finding the passageway to the next floor and satisfying hunger.

The game is viewed from the top down as all objects on the screen move at the same time.

Chocobo can equip a single weapon and armor item, while the hunger level is satisfied by eating different forms of nuts.

Spells can be collected, while successive casting increases the proficiency in that spell.

Unlike other Mysterious Dungeon games, Chocobo keeps his level and stats between trips to the dungeon.

Boss monsters wait at the completion of most objectives.

Different sub-quests are available from the residents of Monster Town.
