Shoal Cave is a unique cave that has a different appearance depending on the time of day. This is seperated by the tides, High Tide and Low Tide. In High Tide, between the hours of 09:00-15:00 and 21:00-03:00, there is a lot of water and the item Shoal Shell can be obtained. Meanwhile, in Low Tide, between the hours of 03:00-09:00 and 15:00-21:00, there is no water giving access to even more floors including an ice filled one with rare Pokémon.

In the absolute basement when the tide is out, you have access to the special Icy Rock. If you level up an Eevee around this rock, then it will evolve into Glaceon
