Luna: ClesTIAAAA!
Celestia: I know, I said I was sorry… Betting with Discord was a bad idea… But I was sure I could win.
Twilight: Princess… I respect you and all that but, the next time he offers you a giant cake don’t bet our butt’s on it.
Cadance: At least there’s no one around to see it.
Discord: Allow me to fix that Cadance SNAP
