One of the more unique functions brought in by Pokémon Gold & Silver is the ability to decorate your room. This feature continued on in later games within your Secret Bases, but this was the first one to implement it. Unlike the later games, this room only has a vew categories for you to fill up your room with just one item. As such, the customisation is minimal

To get the items, for the most part you just have to use Mystery Gift with other Pokémon Gold, Silver or Crystal players, or utilise the Mystery Gift feature of Pokémon Stadium 2; your mother may also purchase certain items. Incidentally, you can view your room's decorations in full 3D within Pokémon Stadium 2

To change the decorations, you just need to access the PC in your room. The decorations you can place are as follows:
