A cave found on Penrith Isle's beach, partially filled with seawater. Due to the shifting of the tides, aquatic Pokémon can be found out of the water inside.

??? (???)
This is the only location in the game where wild Goomy can be found, making it necessary for the research quest on showing Dr. Thorne a Sliggoo or Goodra.
It is also the first location in the game where players can encounter Water/Poison Qwilfish, making it useful for that research quest as well.
After visiting Central City, players can find an Alpha Sliggoo in the south-west corner of the cave, which can be used to complete Dr. Thorne's quest.
