Four Island (Japanese: 4のしまIsland 4) is a small town located on the south-west side of Four Island. It is the most isolated of the seven cities of the Sevii Islands, as, quite literally, there are no routes connecting to it. The only other towns with this distinction are Unova's Anville Town and Kalos's Kiloude City.
Four Island is the home to one of the two Pokémon Day-Care Centers of FireRed and LeafGreen. As the other daycare on Route 5 only allows for one Pokémon to be raised at a time, Pokémon breeding is impossible until the player has reached Four Island, which itself is impossible before the Elite Four have been defeated.
Move Tutor
A man on the island will offer to teach one of the player's Pokémon Body Slam, formerly TM08 in Generation I.
The easternmost side of Four Island houses the entrance to Icefall Cave. Unlike the normally tropical and warm climate of the other Sevii Islands, Icefall Cave is extremely cold. HM07 (Waterfall) can be found here. This is the place where Lorelei caught her very first Pokémon, a Lapras.
When the player first arrives, the only thing to do is to explore the inner first floor of the cave. Many ice tiles are scattered around, causing players to fall through once they are stepped over twice. There is also slippery ice, causing players to continuously slide in the same direction they stepped in. After much navigating, HM07 (Waterfall) can be obtained. Once the player uses the HM to scale the waterfall to the back inner cave, Lorelei of the Elite Four will be found confronting Team Rocket grunts. The player must help her to defeat them. After they are defeated, Team Rocket will flee to their base on Five Island and Lorelei will temporarily stay in her house on Four Island.
Lorelei's house
Lorelei, the first of the KantoElite Four during Generation I and Generation III, lives in Four Island. She grew up on the island, even catching her first Pokémon in the local Icefall Cave. Her house is located in the eastern side of the town. She collects stuffed Pokémon dolls that she keeps in her house, and every time she goes out, she comes back with even more than last time.
Braggart's House
Located next door to the Poké Mart, the Braggart hands Trainer Card Stickers to Trainers who have made accomplishments in the games. There are three different stickers, with four levels each:
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
