Hair cut Brothers.

Question

You know how there's a cheap one, and an expensive one? does the cheap, lower quality one raise your pokemons happiness by less than the good one?

Answer 1

Yes. The brothers give off the following happiness values, but it's based on your pokemon's current happiness:

                        0-99          100-199       200+

younger brother +10 +3 +1

Older brother +5 +3 +1

as you can tell,. the younger brother gives more if your pokemon's happiness is pretty low from the start. so if your pokemon has a happiness of at least 100, just go with the younger brother, since he's cheaper.
