Since the PVC ponies lack a Fluttershy (no, the recolored Rainbow Dash does not count), I took it upon myself to make one.
The figure was sculpted in Super Sculpey, cast in resin and then painted using acrylic paints.
Fluttershy is in scale to the PVC figures, but has a much more show-accurate design.
EDIT: Copies of this figure, both painted and unpainted (for those whoŽd like to paint/ modify it themselves), are available. Just contact me via email (email@example.com) if you are interested.
