Mirta is a sweet witch who would rather have fairy and witch all get along, whose personality is similar to Flora's, with a good head on her shoulders. At Cloud Tower, Mirta was also very alone, not fitting in, however nice she may be to everyone else.
After Mirta saved the Winx girls from the Trix sisters, Icy, furious, turned Mirta into the world's cutest pumpkin. As a pumpkin, Mirta was cared for by Flora, trying to find a spell to change Mirta back into a witch, and finally succeeded in doing so. Mirta and Flora have a special bond between each other.
Mirta has, or had, a friend at Cloud Tower named Lucy, though Lucy defriended Mirta, not wanting to be seen with a "loser," as Mirta was known by her peers at Cloud Tower.
