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, 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.
