Rescue Team Base
In Pokémon Mystery Dungeon Red & Blue rescue team, the Team Base is the house where you have your bed and mailbox. Later in the game you get your team base redecorated by a team of mankeys in exchange for peeled chestnuts. The appearance of the redecorated team base changes depending on what Pokémon you started the game as. When you are at your team base it shows your location as (Rescue team's name) Team Base. From your team base you can access Friend Areas, Dungeons, and Pokémon Square.
Bed and mailbox
Your bed is where you can save your game at any time before you enter a dungeon. It is also where you wake up every morning after having adventured in a dungeon. The mailbox is where you recieve your mail. Mail can consist of either Pokénews or rescue requests. From your mailbox you can organise your missions, accept or decline rescue requests as well as read and store Pokénews.
The rescue team base's appearance will differ depending on what Pokémon the main character is. It starts as one of five basic appearances and is later built into the shape of the Pokémon's head.
