When Queen Galaxia asked Rainbow if she’d like to assist her in her royal duties for a day, Rainbow leapt at the chance.  
Though there was a lot more on Galaxia’s to do list then she ever could have imagined. As the Rainbow maned mare sat stumped on how to go about completing each task that day, our good queen took it upon herself to have a little fun with the Nintendo butt.
 
So that’s how she stays sane with so many duties, by adding a little bit of fun to her days whenever she can, brought forward in most part from the Celestia and Cadence side of this fusion and kept in check by Twilight and Luna for when the work really needs to get done :P (Lick)
 
An excellent description and piece done by the lovely RainbowTashie :iconrainbowtashie:
