“Why is the rainbow horse on the counter?”
“She likes to be tall.”
This is just one of those things about Rainbow Dash you start to notice the longer you watch. If there’s no story-related reason for her to be at ground level, she won’t be, even if she’s just hovering in the air. This is especially noticeable in group shots, where all the ponies are standing together but Rainbow Dash is always hovering over them.
The ground is for losers.
I know this is one of the more noticed details, but I still love it. It fits perfectly for Rainbow’s character, and it’s so natural because no one draws attention to it in the show. It’s just something she does that as far as we’ve seen, most pegasi don’t. Whether it’s so she’s ready to rush off on an adventure or into a race, or just because flying is her greatest passion, so she’s always pushing to do it as much as she can, it’s such a great detail that Rainbow’s hooves hardly touch the ground.
Also she perches like a birb and that’s just adorable.
