Chatterbox

Chatterbox is an earth pony mare that, as accurately named, is very chatty. At one point in UmbreonLeGreat's series she wore a fake horn for a few weeks to mock all the unicorn members of the Umbraverse Mane 6 (playfully, of course). She is the element of loyalty in the Umbraverse. She wears pink eyeshadow all the time and is rather vain, but is also very calm (unless anypony messes with her makeup) and likes to play jokes on others occasionally. She lives in Canterlot, unlike the other Umbraverse Mane 6 who all live in Ponyville. She first appeared in a fanfic instead of an episode.
