Looks like Scoots was a bit confused! Great idea, and I honestly did think of that during the episode! Your designs are fantastic, and the CMC's are no ecxeption. I love Sweetie as Rarity, you just know it's her face, althought ht epnly problem with the design is that Sweetie's back hooves look a bit anorexic, and Scoots a bit chubbby. Applebloom is probably the best one drawn, how you could make her look half Applejack. The joke cracked me up specially because I thought, "Well, Scoots has to be helping with Dash", and then I say this and my heart melted. So in conclusion, a wonderful piece of vectoring and design, with a strong joke! 9/10!
The fashionista explanation would've made more sense, but, as far as I know, we instead got a plot hole. Lauren Faust must be so proud to have a writer/editor as poor as Meghan McCarthy contributing to the running of her once prideworthy franchise.
