Garrtail was one of Gabool the Wild's searats, and a simple rat who was not too bright. He was also known to be a gossip as he told Saltar about his brother's death. He became the captain of the Greenfang after Bludrigg had been slain. Garrtail and his crew were the first to catch up with Greypatch and the Darkqueen; Garrtail immediately ordered his crew overboard to chase the fugitives, but was killed when Greypatch slung a marlinspike into his face.
