“In Castelia City, you can find two massage therapists: Massage Mary. Once per day, you can pay one of them to give your Pokémon a relaxing massage, which will increase its Happiness (friendship). An animated dummy of your Pokémon will appear to show it enjoying the massage! Mary is cheaper and offers very balanced odds. If your Pokémon's Happiness is below 199, you have roughly a 1/3 chance for +1 point, a 1/3 chance for +3 points, and a 1/3 chance for +5 points.”
