The Island Cave (Japanese: 小島の横穴 Islet Cave) is a location in Hoenn on a small island on Route 105. Regice resides in the innermost chamber.



To get to Regice, the Sealed Chamber's puzzle must be completed. After this has happened, the ruins can be accessed.

To open the door in Pokémon Ruby and Sapphire, once in the lobby area, the player must read the Braille inside and simply stand in the same place for two minutes without touching the game. The door will still open even if the game's internal battery has run dry and clock-based events no longer occur, as it is based on two minutes of recorded playtime. The Braille reads: "Stop and wait. Wait for time to pass twice."

To open the door in Pokémon Emerald, once in the lobby area, the player must read the Braille inside, then make a lap of the chamber, sticking close to the walls. The Braille reads: "Stay close to the wall. Run around one lap."

To open the door in Pokémon Omega Ruby and Alpha Sapphire, once in the lobby area, the player must read the Braille inside and stand in the same place for two minutes without moving. The Braille reads: "Stop and wait unmoving as time passes you by twice."


In Pokémon Omega Ruby and Alpha Sapphire, the player is able to encounter Regigigas in the Island Cave after capturing all three legendary giants in their respective locations in that game. To do so, the player must go to Pacifidlog Town and speak to the girl in the northeast house. The player must also have a nicknamed Regice holding an ice-based item (a Casteliacone, a piece of Never-Melt Ice, an Icy Rock, an Icicle Plate, or a Snowball), as well as Regirock and Registeel in their party. Regigigas can be encountered starting from the day after catching the last of the legendary giants, but cannot be encountered at night. As Regigigas is not in the Hoenn Pokédex, it can only be battled after dealing with GroudonOR/KyogreAS.

If all of the above criteria are fulfilled, upon walking into the center of Regice's room, the following message will appear:

"The very earth is quaking! Is something approaching?!"
"Zut zutt!"

The battle with Regigigas will then start immediately.

If the above criteria are not fulfilled, but the player has caught all of the legendary giants in that same game, the following message will appear instead:

"There seemed to be some presence here, but it disappeared in an instant..."

Ruby & Sapphire arc

In The Beginning of the End with Kyogre & Groudon XIII, Glacia was stationed at the Island Cave as a part of Steven's plan to unseal the legendary giants. Despite Glacia's best efforts to open it, the seal wasn't undone until A Royal Rumble with Regirock, Regice and Registeel II, where Steven figured out the key to unlocking it.
