When the dragons are causing havoc and are a nuisance to the villagers. Hiccup comes up with a plan that includes training dragons. He takes up the arena where they once used to fight dragons (without the permission of his father) and starts the training. He tells the gang that the dragons are out of control and they have to do something about it. Hiccup demonstrates with Toothless , showing how to make a dragon drop food that he is not supposed to have; by scratching their chin and gently taking the food item away.
