Bubble Berry asks Rainbow Blitz for advice on how to be manlier. Also, Dusk Shine's nemesis plots his revenge, and a mysterious creature attacks Ponyville.
This is set in the same universe as "On a Cross and Arrow." Gender swapped ponies, for the uninitiated. Because this story really wouldn't work if Bubble Berry was Pinkie Pie.
I think that even if the genderswapped ponies have the same personality, the fact that society treats people differently based on gender means that their stories might be slightly different. This is a story which is only really possible in the Cross and Arrow Universe.
Spoiler: I haven't actually read "On a Cross and Arrow". I've been meaning to. No time.
My submission for the February Write Off.
