While Winter Wrap up is arguably better in isolation, At the Gala would work way better as a bookend to the series.>>36830268
That is great.
I mean we've seen Twilight doing Pinkie (Hearth's Warming Tale), Rarity doing Pinkie (Gift of the Maid Pie), Fluttershy doing Rarity (Fake It Till You Make It) and Rainbow doing everyone else (Newbie Dash)
I may have forgotten some. Still, those moments were great but too brief. A whole episode of that kinda stuff will be so fun.
G1 did their own bodyswap episode and despite a less talented and diverse voice cast doing it with less developed characters, it was still a lot of fun to watch. And that was G1. Imagine how fun it would be with G4!
