Twilight Sparkle anxiously prepares Ponyville for a visit by Princess Celestia. During her preparations, Fluttershy finds a cute creature called a Parasprite and takes it back into town.
This episode was originally called "Pied Piper Pinkie", but was then changed following a later story meeting.
According to Lauren Faust, Swarm of the Century was "initially conceived as just a story about a plague of locust-like creatures, but the parallels to Tribbles became apparent pretty fast. I'm a huge Star Trek dork," she wrote, "so we went with it."
Writer M. A. Larson added that he had Gremlins in mind when writing the episode.
A small part showing Pinkie trying to lure the parasprites away from Ponyville with her instruments reappears in Cakes for the Memories.
