Diamond Tiara visited a new costume shop in Ponyville. She was getting ready for another formal but dull party her mother was throwing at their mansion, which Diamond and Filthy were not very fond of but had no choice but to join in. When the shop owner asked what she wanted, Diamond asked for something that may liven up the party. The shopkeeper smiled and placed a clown nose on her face.

Diamond felt a strange sensation throughout her body as her mind start thinking crazy thoughts. Clothes formed on her body while her mane was covered by a silly wig. Her face changed to that of a lunatic as she start laughing uncontrollably, and once it was over, the shopkeeper showed her a mirror. Diamond smiled and paid the shopkeeper before pulling a horn out of thin air and honking it. She left and made her way home where she was ready to put a smile on everypony’s face.
