De-lurking to say... I think our dear Twily might have been a little lankier already last season. In fact I think there were a couple instances of the animators playing with pony heights. We knew from Sweet and Elite that Spitfire is supposed to be smaller than the other Wonderbolts. And when she shows up in Rainbow Falls, there are several shots where she definitely looks smaller! It really could be my imagination, but it makes sense that there would be different body types amongst the ponies and if the animators have the means and the budget to portray that, then more power to them!
