They're based on Pokemon, they were in an old Pokemon magazine. but these characters don't exist anywhere beyond this series of GameBoy colour skins.

Some of them like The bull, crab and fish are clearly based on real Pokemon, but the others I'm guessing they just made them up as there weren't any pokemon to fill these zodiac signs at the time they were made.
