Long before the events of Chrysalis' attack on Equestria, a worse fate struck the Hives of the nation.
The Joyous Hive, responsible for the always important celebrations and joy in many parts of Equestria, vanished without a trace. The Hives of Equestria began searching high and low for them, with very little success. Hope of finding them was all but lost, until one Changeling was found.
Surprise, a male Changeling from the lost Joyous Hive was found in Ponyville, and after the events of the Ponyville attack, he now works alongside Pinkie as an honorary member of the Pie family. He loves Pinkie and the new life he now has, but something is missing...
Surprise couldn't be happier to have a family, but he still feels a loss of his Hive, and after a trip to Pinkie's Family Farm, the feeling gets worse. Pinkie finds out, and decides to help her friend. How? By traveling to every big city in Equestria until they find something, of course. What could possibly go wrong?

Takes place during the Artist Hive portion of "A Day In The Hives"
