Will some one please tell me how to get a crobat! I know it evolves from..

It evolves when it's happiness becomes really high. Then let it grow a level and it'll evolve.

The Golbat has to be very happy with you....to increase happiness, you can

- have Daisy (Gary's sister) groom it for you
- bring it to one of the haircut bros.
- walk 512 steps
- have it gain a level
- give it a vitamin/HP up.

Avoid:

- having the Pokemon faint
- giving it bitter medicine

Ok, ak-47 is right but doesn't give a specific answer. Golbat's happiness has to peak and then it will evolve. You can increase this hapiness by giving Golbat haircuts regularly from the Underground and then training it. Or you can speed up this process by catching Golbat with a friend ball. Either way, these make it's happiness go up and it will then evolve into Crobat.

To get a crobat you need to train globat till about level 50 maybe more then it will evolve the same way chansey evolves to blissey

Happyness
Give it hair cuis daliy
One place for cuts is in goldinrod
Under ground
Go talk to the guy behind the counter

One is in pallet town garys place go in there between 3 & 4
Talk to the girl

Then after about four or five cuts go to goldenrod

Go to the place above the bike shop
Have golbat as the first in your party talk to her
She will tell you how happy it is when it is up past DELIGHTED
Level it up

To get a Crobat, capture a Lv 50 or higher Golbat then train it till it likes then it should evolve at Lv 62.

Get your Golbats haircut by the hair cutting brothers in Goldenrod city. Let your Pokemon be involved in battles without fainting. For The later stages of the game feed it vitamins ( berries and rare candies also work, however some berries reduce, and rare candies offer no ev gain. 🙏 hope this helps
