Oh no! Twilight's accidentally cast the cutie mark switch spell again, and now all the ponies in Equestria have their cutie marks switched with somepony else's! This time though, the spell lasts for 24 hours and there's no way to undo it! Whose cutie marks would you like to see switched, and why? Mine would be Applebloom and Scootaloo :Trollestia: Kidding, probably Shining Armor and Rarity, because I'm sure she'd kick a load of butt as captain of the guard.
Twilight Sparkle and Zecora. It would be amusing to watch the best magic users in Equestria struggle to use each others magic.
Derpy and Cadance, just so I can see Derpy flying all over Ponyville to give hugs to those who need love.
