“On a scale of one to me, I’d have to admit, yeah, this place is pretty awesome already… but it could always be a little more awesome. So, live from the moon, I, Rainbow Dash, do hereby claim this part of it to myself, now and until forever!”
 
“…she genuinely can’t be serious about this, can she? Really, when will she learn…”
 
So, after getting her suit emptied from all that helium last time, Rainbow Dash was finally able to set her hooves down on the moon… and promptly claim a section of it for herself. Obviously, Princess Luna is none too pleased about that.
 
Funny thing about these space suits, there’s a little knob on the back that controls how much air the life support system pumps out into the suit at any given time - easy for unicorns who’ve had time to study the suit layout to control, not so much for anyone else by themselves. It also just so happens it’s very clearly marked, so someone can always fiddle with it when they need to.
