It is unlocked after the members of the Wigglytuff Guild set off on an expedition to find Fogbound Lake. Bidoof will accompany the player on the first visit. During the player's first visit, they will have the choice between Craggy Coast and Side Path. If they choose Side Path, they will have to traverse five additional floors, then bringing the player back to the crossroads between Craggy Coast and Side Path. Traveling through Side Path will bring the total number of floors to 14. This dungeon is the first to have treasure boxes dropped from fainted foes in these games.
