Time now to cover the topic of the kiddies . What makes work so well, I think , is that they actually act like kids without falling into exagerations . Besides these may be the closest ones ,in revamp, to their actual designs in the show.
As foor what they re doing right here , Applebloom tries to obtain a predefined cutie mark (who knows ? Maybe you can get them ), Sweetie Belle explores the apex of her singing abilities (by singing "THIS":https://www.youtube.com/watch?v=HgzGwKwLmgM of course ! And as you can see Applebloom was responsible for recording... ) and Scootaloo tries to fly (Yes , I know of her inability to fly high up the skies , but I don't think it would stop her from trying anyway . Though don't worry, her friends are ready to fix her up . )
