It occurs to me: Natives of the human world have never seen ponies. (I guess unless they spotted one looking through the dimensional holes in Friendship Games.) They need to finally meet their untransformed counterparts. Even them visiting Equestria and experiencing being ponies would be great. Though, I would declare it the best of the EG movies if human Fluttershy gave pony Fluttershy pettings and/or snuggles and/or bellyrubs.
