Description from his deviantArt page:
Happy weekend, everyone! I’m posting this a little early due to attending Nightmare Nights. Fun time, but I didn’t want the finale to come and go without a good night from our pink pony.This is not the end. I’m not able to do this every week, but I intend to at least celebrate Pinkie once a month. :)
She will still be with us, in Derpibooru…
I think your little vignettes were more gratifying than some of the main events.
Good Night for now, Pinkie.
Or you know, given the time…Good Morning.
Maybe not that long, going by the description.
