In a world filled with talking Pokemon, Red and Green compete with each other in a race to gather all the data needed for the new Pokedex! Bumbling Clefairy frustrates Red with its extreme incompetence and silly behaviour... however, sometimes Clefairy's bizarre ideas to work out in the most surprising ways!!
