Really good

IŽd personally would put more abilities to them (In the movie, they unleash the prince, conjure items, enchant a sword, transform rocks to flowers, make a rainbow-shield, transform the crow in a statue, animate objects, change the color of the cake (and the dress)... you get the idea).

Anyhow, I never even thought about making a PrC for this, I am really amused.
A well-headed project if you ask me. Really flavor-full
