There was a movie that I use to watch when I was younger and it was about a gnome or a troll or something that left his house one day on a quest. I'm not sure if it was by choice or not. I think maybe he had a visitor. He ended up having to slay a dragon. Or maybe he was the dragon and he had a cold and kept catching things on fire when he got nervous. He ended up going into town and getting nervous because everyone was screaming and he caught something's on fire. Anyway, at the end of the story the princess fell in love with the dragon and they had a picnic or something and walked through the town
