Life in the new castle took some time for Twilight Sparkle to get used to. But she's starting to settle in with the help of her marefriend, Rainbow Dash. Until a chance discovery has interesting implications for locksmiths everywhere when Twilight gets locked inside her own bathroom.

Unable to teleport out, she brings the lock to life and tries to find out how to open it. Rainbow Dash, hearing the opportunity for an epic prank, can't resist.
