Now for the Rainbow Dash and Quibble Pants kids. I felt them each having their own cutie marks made more sense. I wasn't a huge fan of the idea of the CMC each having the same cutie marks, but it at least was different. Anyway I initially it would be cute if Connie and Plume had similar cutie marks like them, but honestly? that just doesn't work for them like it did for the CMC. So lo, there goes my over-explaining nature.
