It's somepony's special day and everypony in town expects Pinkie Pie to throw a party-riffic party for the birthday pony. When they don't get invitations in the mail, they start to wonder just what is going on inside that mare's head. Thinking nothing's really wrong and she simply forgot the invitations, everypony goes about their daily business until the unofficial party time for the town when a few ponies head over to find a normal looking Sugarcube Corner. Just what's going on and why isn't the party pony partying?

Random one-shot to celebrate my birthday. Sadly, I didn't get it finished in time to post it. Oh well, it's up and that's all that matters.
