In Pokémon Mystery Dungeon: Blue Rescue Team, you can access the Seafloor Cave by completing a specific story event. After finishing the main storyline and rescuing the Legendary Pokémon, Kyogre, you will receive a letter from a character named Wigglytuff. This will unlock the Seafloor Cave, which you can then access from the beach area. Be prepared for tough battles within the cave, as it contains challenging Pokémon and a variety of floors.
