Troll Tapestry

An enormous moving tapestry depicting Barnabas the Barmy's foolish attempt to train a group of six trolls for the ballet hung on the seventh floor of Hogwarts School of Witchcraft and Wizardry, opposite the entrance to the Room of Requirement. The small group was portrayed by a forest clearing, and some of the trolls were hitting Barnabas with their clubs.
