Four Island is also host to a very large Pokémon Day Care run by an elderly couple. For a small fee, they will watch after a Trainer's Pokémon and raise their levels. Unlike the Day Care on, two Pokémon can be dropped off. Leaving compatible Pokémon at this Day Care will result in a Pokémon Egg being laid.

It is freezing inside the cave, due to the high population of Pokémon that live there. For this reason, it is known as Icefall Cave. During, Team Rocket arrives here; however, with the help of the player, Lorelei and her , whom she met in the cave during her youth, are able to drive out the villains to their home base on Five Island.
