Dear All Pokemon fans,
Haven`t you ever though that the appearance of a Pokemon`s evolution doesn`t look like a thing it used to be?
Take a look at this awesome fan-made video, which may give you a good answer to those odd evolutions. It breakdowns the process of some Pokemon`s Evolutions!
Its available in Japanese only, however is completely understandable by just looking at the visuals!
Cheers out, Enjoy!
PS: Exeggcute was very persuasive!
