He was a creature unlike any other, with green skin, bulging eyes, and a crooked nose. Grug lived under a bridge that spanned a fast-flowing river, and he spent his days scaring people and demanding tolls from anyone who dared to cross his bridge. Grug was not a happy troll.

But whenever he tried to make friends, people would scream and run away, terrified of his appearance.
