Hoddergruff Gropeknot was a woodtroll from the same Deepwoods village as Twig. He was born within a week of Twig, and they grew up together as neighbors and friends. However, during one trockbladder match in which Twig left the path to score, Hoddergruff betrayed Twig and joined with all the other woodtroll children in taunting and hurting him.
