Forest troll

From the One Wiki to Rule Them All, the Lord of the Rings Encyclopedia.

Forest trolls are extremely large troll that live in a small forest just before Imladris.

As discovered by Bilbo on his visit to the Lonely Mountain, they are so sensitive to sunlight that they are instantly frozen and turned to stone if they are exposed before it. They are believed to be the most intelligent race of trolls to live, being capable of speech.
