The path leading to "Fawn's Butterfly House" includes butterflies, fairy Iridessa (I'd mislabeled her on my last update as Fawn - I am definitely no Pixie/Fairy expert!), and Fawn is in front of the Butterfly House.  The Disney website had made it sound like the Butterfly House would be expanding, but it's the area around it that has - the Pixie Hollow Fairy Garden surrounds the Butterfly House now.
