Chimecho does not have a confirmed evolution yet.
It has, however, a pre-evolution called Chingling and in order to get it, you must breed a Chimecho while holding Pure Incense. You can always find Chingling in the wild but it's very rare and it only appears in Diamond, Pearl, Platinum, HeartGold and SoulSilver.
chimecho doesn't evolve
Chimecho is unable to evolve as of Pokemon X and Y. Chimecho does evolve from a Pokemon called Chingling when it's at max happiness and during night time.
chimecho when you increase it's happiness and grows a level
Chingling evolves when it's really happy with you.it doesnt evolve
it has to have enough happiness at nighttime, then it will evolve into chimecho.
you can't evolve him that's his final evoloution
You must evolve Chingling.
Maxed out happiness in the daytime
Catch chingling in Mt. Cornet. then evolve when happy at night
get a chingling on mt coronet and evolve it
Chingling must be leveled up at night with high happiness to become Chimecho.
chimecho does not evolve into anything else, but it does evolve from a chingling. To get a chingling to evolve, you must level it up with a high enough friendship, (by feeding poffins to it, winning battles, spending time outside the PC, and going to the spa on the battle frontier island). BUT you must level it up between the DS's time of 8 PM and 3.59 AM. Hope this helps!! =]
