Geography
Shoal Cave is a cave north of Mossdeep City. This cave was carved into the side of a rocky mountain rising from the ocean. At predetermined times of the day, every six hours, the tides rise or fall. During high tide, the cave floods, allowing the undefined to use to access levels of terrain otherwise out of reach on foot. Conversely, during low tide, the receding waters allow the player to descend to levels that would otherwise be underwater, most notably the ice floor at the lowest level in the cave. This icy room contains the Never-Melt Ice, and can only be accessed if the player has. Near the entrance to the icy area is a who gives away a Focus Band.

In Omega Ruby and Alpha Sapphire only, the Ice Rock is located in the icy room, which allows to evolve into.

Tides
Once the player enters the cave, the tide will not reset until the player leaves the cave and attempts to re-enter.

Obtaining the Shell Bell
Four Shoal Salts and four Shoal Shells are found in the Shoal Cave; the Shoal Salts are available during low tide and the Shoal Shells are available during high tide. If the player has four Shoal Salts and four Shoal Shells in their Bag, the undefined can give the materials to the old man in the first room to make a Shell Bell; the old man can make any number of Shell Bells, as long as the player provides the necessary materials each time. This is the only way to obtain Shoal Salts and Shoal Shells in the Generation III and VI games.

Immediately after crafting a Shell Bell for the player, the old man prompts the player to find the ingredients for another. However, the player must wait for the tide to change in order to gather the salts and shells again.
