A few years ago, when I was younger I use to watch this cartoon.. but I don't know the name of it! Its been killing me. Well I only remember a little about it, all I remember is a boy and a girl walking through the woods and find a carnival or something, and there's weird creatures like goblins... its not much but I hope someone can help me!!

Could you be thinking of the end of the movie "We're Back: A Dinosaur's Story"? The two main characters (a boy and girl) travel to a fear-based circus with people dressed in goblin costumes.
