Change your Pokemon's color!
If you nickname your Pokemon in the Gameboy game and bring it into Stadium, it will have changed color depending on what you nicknamed it!
This has NOTHING to do with shiny Pokemon, because they were not invented when Stadium was released.
Possibilities range from an orange Pikachu to a seagreen Tentacruel.
