Rapunzel vs Frankenstein

When Rapunzel discovers Dr. Frankenstein's castle she is just looking for some medicine for her cold, but contact with one of his chemicals causes her hair to grow and come alive, along with the clay "monster" in his lab; Frankenstein is horrified at his own success, and it is up to Rapunzel to convince him and the towns' people that neither she nor Clay is really a monster--and that living hair has some advantages.
