Being stranded on a deserted island leaves Pinkie Pie bored, lonely and without hope. As she prepares to end it all, she suddenly spots a mare laying by the shore. It's Rainbow Dash! Unfortunately, she is dead and quite flatulent. Pinkie Pie makes a miraculous journey, dragging the talking corpse of Rainbow Dash along along for the adventure. There's just one catch… Rainbow Dash doesn't know what a party is? …yes Pinkie, and she doesn't remember who she is either.
