Pinkie Pie has always been strange, but now her unique behavior has landed her on the psych ward. Her friends are distraught, of course, but none more so than Rainbow Dash. The cyan pegasus is unable to function in daily life without that ever-present party pony by her side. So when Twilight finds a spell that can save their friend, will Rainbow be able to risk the ultimate sacrifice? Will she be prepared to enter the mind... of Pinkie Pie?

Short oneshot I thought up for my creative writing final. It's my first MLP fanfiction (at least, the first that's fictional). Credit for the cover goes to Canor98 of Deviantart.
