Here's is your house, which serves as your base of operations in the Pokémon Dream World.
Spend berries in the Dream World to purchase furniture for your house, which also features a board that keeps track of the Pokémon you befriend in the game.
Unlike previous Pokémon games, you can't grow berries in Pokémon Black and White. For that, you need to log into the Dream World and tend your garden.
This is the sharing rack. If you place items you wish to trade on it, friends that come visit can swap them for their own treasures.
This is what it looks like when you have friends in the Pokémon Dream World. I have no friends.
Here is the island of dreams, where you can explore, uncover rare items, and befriend wandering Pokémon by playing mini-games.
Once you befriend a Pokémon you can bring it back into your copy of Pokémon Black and White, but only one can be transferred over per day.
