Pokémon Ruby and Sapphire/The Shoal Cave



Shoal Cave is an average size cave, accessible only from ../Route 125/ (and by extension ../Mossdeep City/). It is unique in the fact that it is the only cave in Hoenn to have a significant tidal clock - so significant, in fact, that the traversable area of the cave doubles during Low Tide. In order to check whether it's high or low tide beforehand, Trainers can speak to Sailor Ernest on Route 125.

Shoal Cave is also the only location in the region where and  can be found, which are both required for a unique item, and thus have their own section.

In order to fully explore the cave and all it has to offer, it is recommended that Trainers bring Pokémon that know and.

The Tides
Shoal Cave is the only area in the game to use a tidal system - what areas of the cave you can access changes depending on what the tide level is.

High Tide
During high tide, only the first two rooms are available - and even then, you can't get everything in those two rooms.

Items

 * - Room 1F-1, in the northeast, accessible from the inner room.
 * - Room 1F-2, east of the central ledge.
 * - Room 1F-2, on a ledge just north of the southern bridge.
 * - Room 1F-2, on the north-western ledge.
 * - Room 1F-2, on the north-eastern ledge.
 * - Room 1F-2, on the south-eastern ledge.

Low Tide
During low tide, you gain access to the rest of the cave, from the previously unreachable areas at the start to the icy depths at the bottom. This is also when you can get unique items, so it's definitely worth it to explore the cave at low tide.

Items

 * - Room 1F-2, outside the western exit from the lower room.
 * - Room 1F-2, under the northern bridge.
 * - Room B1F, in the southeast corner.
 * - Room B1F, east of the ladder.
 * - Room B2F, in the north and near the center.
 * - Room B2F, given to the player by the Black Belt.
 * - Room B3F, on the elevated floor.
 * TM07 - Room B3F, near the ledge.

Shell Bell
If you collect 4 Shoal Shells from high tide and 4 Shoal Salts from low tide, a man in the cave entrance will give you the, which restores the holder's HP by an eighth of the damage the holder just dealt.
