A witch comes to berk asking for a place to stay for free since she has no money when she really does. Hiccup being the chief allows her to stay in return she entertains the people of berk with magic tricks for money. Hiccup and Toothless snoop around her hut and find something unexpected, (sorry for the clickbait). The witch isn't pleased with them and gives Hiccup a curse to become a vampire until she lifts it.
