Obviously, if you're trying to raise happiness, you're either doing something very wrong, or you're making your Pokemon hate you on purpose (I recall a particular Jigglypuff I made hate me.). Could you try being a little nicer to it?" LGFR: "I don't like the way it glares at you. is there some reason your Pokemon would hate you so much?" LGFR: "Umm, it's not easy for me to say this, but.

When their happiness quota has reached 220 or greater, they will evolve the next time they level up with experience or by Rare Candy. The following Pokemon evolve by happiness. For a select few Pokemon, evolution can be achieved when the happiness value is maxed out and the Pokemon gains a level after achieving max-out of happiness.
