I checked the video again on Youtube, so I can see it's not a old Fletchling design haha, I guess it's a Woodpecker, that can defiantly learn Drill Run... and I saw another Pokémon it's unclear for me what it is but I guess a Bug type... but not sure!
Also the building with the Horsea fountain, have a Chinchou, Spheal poster on it... maybe a Water show or gym ( But I guess not, because I didn't saw the gym sign bord... )
But the buildings remind me a lot of houses from England, so maybe it's the region that have fought against Kalos in the war?
And the cars are cool too, imagine that Nurse Joy will pick you up to the Pokémon Center! xD
And the Safari car [roadtrip all the way]!!!
But I will pick for now Pokémon Moon, [ no idea why ]
