POOF!
Princess Celestia: "Good morning, Octavia! I have a job for you."
Princess Celestia: "I need you to clear out a few slimeballs around Canterlot."
Octavia: "Slimeballs?"
Celestia: "Yes, I'm unsure how those things keep appearing around Canterlot and Ponyville. It could have something to do with the Everfree Forest, but Fluttershy hasn't seen anything leaving from there. So I'm leaving this in your hooves. Do be careful! They can be quite jumpy."
