Edit
A background character in "My Little Pony: Friendship Is Magic" who has curly pink and dark blue hair, often depicted with Lyra both during the show and in fan works. In fan works, she is portrayed as being calm and conservative in her actions, and tries to keep Lyra's obsessions from getting out of hand (if you'll excuse the expression.) Every time she has had a speaking role on the show, she has had a noticeably different voice, fueling speculation that she may be a voice actress or shape-shifter, that the show's crew are deliberately changing it each time, or that the producers are trying to get every woman on the show's crew to voice her before the series ends. It's more likely, however, that this is simply an oversight.
In the hundredth episode of the series, she revealed herself to be former secret agent Sweetie Drops, and also seemed to have a very close and affectionate friendship with Lyra
