One of the features Gold and Silver brought that's stayed with the series ever since is Mystery Gift. However this Mystery Gift is much different than future incarnations. You can't get Pokemon from this one or even use it at Nintendo events: it's strictly for use with other GSC titles, Pokemon Pikachu 2, and Pokemon Stadium 2. It can only be used once with a unique user with a total of five different users daily.
To unlock the Mystery Gift, you must have a Game Boy Colour. Earlier and later Game Boys don't work as they don't have infrared communications. Go to the Goldenrod Department Store and talk to the little girl on the fifth floor. She will ask if you if you'd like to use Mystery Gift. Naturally tell her yes and you'll be able to from that point on.
In deciding hat you get, you have a 50% chance of an item or a 50% chance of a decoration for your room.
