Sugar Blizzard (Sugar) is the sister of Fluttershy and is not used to going around. Fluttershy shows her sister around and even lets them on a tour to the heart of the Everfree Forest. But shook with terror, Fluttershy leaves when the tourist exclaims that the night was shortly falling. Sugar stays, but then after a short period of running does she realize that her necklace has disappeared from her neck.
Sorry if I made a mistake somewhere, and please enjoy! :)
