Intro. You are another 2 young people in the city of Berk. You go through a workout to become a dragon coach, but before that you need to choose the egg of their respective dragons. Among them are 3 eggs. They are covered. One egg is of a deadly Nadder, the other of monstrous nightmare and the last, the egg of a fury of the night (I know the banguela is the last of the species, but follows the script). So you don't know which egg is which one. So choose. Good luck
