Great, you got me thinking about it and this popped in my head.
This isn’t canon to the blog and I am not at all saying this is how she’d actually respond to being shrunk, but something about tiny bundles of rage are amusing to me
I’m reminded of a fan-fic I read many moons ago, where Celestia went through age regression. IIRC, Luna cast the spell on Celestia but I don’t exactly why. I never did finish reading it. I wish I could the name of this story. Man, I don’t a lot these days. =/
YES! That’s it. Thank you kind sir/madam.
That sounds like My Little Alicorn to me:
