I love MLP it is my non-guilty, guilty pleasure. And while the average joe could probably roll their eyes and easily say 'wtf she doesn't belong here' you've really taken that and shoved it out the window, proving them wrong.
Pinkie is the perfect comic relief and you have engaged her enough to make characters feel moved in all ways; sadness when she died, and happiness with her churro stand. She's a diamond in the rough, and I'm delighted with what she brings here.
