Plot summary
Wirt, Greg, Beatrice, and the frog visit a tavern to ask for directions to Adelaide's house, but Beatrice is forced to wait outside after the tavern keeper throws her out, believing that bluebirds bring bad luck. The people in the tavern warn the brothers about the Beast, telling them that the creature turns people into trees of oil to burn in his lantern. Based on this description, Wirt concludes that the Woodsman must be the Beast. Hearing Beatrice in distress, Wirt steals a talking horse named Fred and rides to her rescue.
He finds Beatrice unconscious next to the Woodsman. Wirt and Greg fend off the Woodsman and ride off with Beatrice. A shadowy figure appears to the Woodsman and reminds him to be careful, that the flame inside his lantern contains his daughter's soul, and that he must cut down Edelwood trees so the fire can keep her alive.
