Fantasy old movie... Name?!

Back (in 2005 or later) when I was a little kid I remember I saw a fantasy movie.
There was a father with his two daughters I think, and they meet a man with horns eating sheep in a castle. Then they become friends and they go out to fight a bad company together. They also have a fight in a ship because of the skull of a dragon.
In the ending a girl raises the dragons skull and the dragon gets formed and kills all of the bad people who were trying to steal it's skull.

If anyone knows.. I'd really like an answer.

Voyage Of The Unicorn (2001)??
