When Sunset, Rainbow Dash and Sci-Twi are in pony form, some of Twilight and Rainbow Dash's details are missing. For Twilight, her eyeglass temples and wings are missing although the latter two were added to a Throwback parody video of Beverly Hills 90210. And for Rainbow Dash, her cap and geode bracelet were missing as well, although her hat might be shown in Hurricane Fluttershy, minus the geode.
When Rainbow Dash exclaims, "It's Hero Time" and slapping her geode that goes on full speed on the water, this is similar to Ben 10 because Ben Tennyson slams his Omnitrix when he exclaim his catchphrase as well as XLR8 running on the water. Interestingly, Tara Strong voices Ben in the series.
