Ice Troll

Ice trolls are similar to Thwarts in looks and function. They fling Brr instead of Fireballs allowing them to be used in different puzzles, but there fire is still deadly. They do however turn out to not be evil in the end, and their leader, Shiver explains why they were attacking you, a little too late. Ice trolls were introduced in Mysteries of Fire Island. They all live on Sundog Island except for Shiver who lives in the Fire Island Volcano.
