When her pony pals are down in the dumps, Fluttershy swoops in to cheer them up in her own sweet and quiet way. She delights in the beauty of friendship and the nice feelings that comes from being nice. Fluttershy is definitely a little bit meek, but she can be fierce when she needs to be. She's faced her fears and grown a whole bunch, and she continues to build her self-confidence! Oh, and she loves her animals. A LOT! Even when they're being naughty little critters. She's probably the most in tune with creatures of the forest of all the ponies she calls her friends.
