Mainly because of Gloriosa’s forest associations, and Lemon Zest’s hair resembling the leaves of a tree, I came up with this ridiculous idea.
 
Here, Gloriosa transforms Lemon Zest into a forest fairy, just like her and her brother, who is trying to help her get used to life with their fairy people. Lemon finds this to be rather weird for her: instead of her typical clothing, she wears a beautiful dress, and she can cause plants to grow and bloom faster.
 

 
I also added Fluttershy as some kind of forest angel, mainly because I like her wings.
