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 has an incredibly unique gimmick, in the form of its tidal clock - about half of the cave is accessible only at high tide, and half only at low tide. While you can simply ask Sailor Ernest on route 125 for the tide, it is much more convenient to use the ingame clock for the tide instead:
 * The cave is at high tide between 21:00 (9PM) - 02:00, and 09:00 - 14:00 (2PM)
 * The cave is at low tide between 03:00 - 08:00, and 15:00 (3PM) - 20:00 (8PM)

When the cave is at high tide, is required to explore it. When at low tide, is required.
