Iceberg Ruins

The Iceberg Ruins is a special room in Mount Coronet in Pokémon Platinum. It is located inside near the exit to Route 216. It is called the Iceberg Ruins because it is the home of Regice, the Iceberg Pokémon. Normally, if the player enters the cave, it is empty. However, after entering the Hall of Fame, if the player has a fateful encounter Regigigas in their party, there will be a 7-dot pattern on the floor and a statue on the back wall.
