(Japanese: シクレレじま Shikulele Island) is a location in Pokémon Ranger: Locus of Light. The island is found directly north of Laiun Island.
The monument can be found in the middle of the island. Because of the need to call upon Latios or Latias in order for players to be able to pass the electric storm above Laiun Island, players must obtain the Ranger Sign to summon one of the Eons. To do so, players must activate five beacons, one of which can be found on the eastern part of the island. After coming back to the monument after all are activated, players will face one of the two Eons in the sky and obtain the Ranger Sign in order to summon them. After finishing the game, the other Eon Pokémon will appear on Shikulele Island during a quest.
