Hungarian Horntail Dragon
Harry returns for his fourth year at Hogwarts School of Witchcraft and Wizardry, along with his friends, Ron and Hermione. There is an upcoming tournament between the three major schools of magic, with one participant selected from each school by the Goblet of Fire. When Harry's name is drawn, even though he is not eligible and is a fourth player, he must compete in the dangerous contest.
Mandrake Root
In the Harry Potter series, the Mandrake Root is the root of a magical plant known as the Mandrake or Mandragora. It's a powerful potion ingredient with restorative properties, particularly used in the Mandrake Restorative Draught, a potion capable of reversing petrification. The Mandrake is a sentient plant with a root system that resembles a human; it matures from a form similar to a baby into a small humanoid adult. The cries of the Mandrake are dangerous; the screams of a fully-grown Mandrake can be fatal, while those of a young Mandrake typically cause unconsciousness. In "Harry Potter and the Chamber of Secrets," the students at Hogwarts use Mandrakes to create a potion to cure those who have been petrified by the Basilisk.
