In this setting Fluttershy is a shaman who speaks and defends the spirits of the land. Fluttershy had two states of being. One was her normal pegasus form, but when the moon is full she transformed into a bat pony and then she would converse with the spirits of the night.
One of Fluttershy constant companions in the dream was Manny the Manticore. The manticore act as both her protector and as her flying mount.
