The Mystery Gift feature of Pokemon Gold, Silver, and Crystal versions is a way of communication between two games. It uses the infrared port of the Game Boy Color to trade items between games. Some of these items are unobtainable without cheats/usage of this feature. These items include: room decorations, special mail, etc.
