When Celestia tells Luna she can't invite a bunch of her friends over for a Let's Play, Luna decides to do it behind Celestia's back. Can she enjoy a Friday night with her gaming buddies, or will Celestia find out?
Luna's Let's Play guest list:
Discord
Princess Cadence
Lyra Heartstrings
Derpy Hooves
Twilight Sparkle

Cheer up, Twilight. It's not every day somepony changes species. In fact, no pony has ever changed species. It's something new and you like discovering new things. Granted, Equestrians don't like new things, especially things that fundamentally alter their government. So maybe there is reason not to be happy after all.
