Children's movie from the 80s (I think)...
The characters were these puppets that looked like trolls or goblins or something. I think the opening scene was at this house where a group of the trolls were singing. Another scene showed the main girl troll walking into a scary forest and she witness the murder of the prince troll. And then she goes back to town to tell everybody. And everybody is sad. But it turns out that the prince wasn't actually dead. It was someone else. I think the prince had this big red ring. And I think the prince and the girl get married at the end.
