Looking to evolve feebas into the fabled "Most Beautiful Pokemon", milotic, in Pokemon GO? Then get ready to put a lot into just this one Pokemon! To start, you will have to mass a total of 100 Feebas Candy. Whether you obtain this incredible amount of Candy by catching loads of Feebas or by using the precious rare Candy you receive from Raid Battles, this could take a bit of time. However, it doesn't stop there! On top of needing 100 Candy in order to evolve, the Feebas you are looking to evolve must be walked at least 20km as your Buddy Pokemon.
It takes quite a bit to evolve feebas, but it is definitely worth it in the long run since milotic is one of the best Hoenn Pokemon you can find. And hey, at least the cost to evolve it isn't as outrageous as magikarp, Walimer and swablu.
