The Greenfang was a ship in the fleet of Gabool the Wild originally captained by Bludrigg. After his murder, Gabool gave the vessel to Garrtail. The latter sailed it towards Mossflower Woods, searching for the mutinous Greypatch in the stolen Darkqueen. The crew spotted the Darkqueen before Greypatch could navigate into Mossflower, and staged an attack. Greypatch's crew members rushed Garrtail's before they could leave the shallows, and, mainly due to some bows and arrows Bigfang found onboard Darkqueen, Garrtail's entire crew was massacred. The searats then shot fire arrows onto the Greenfang and let it drift away.
It drifted north towards the residence of Bobbo. The dormouse saw the craft float into a nearby cove, lacking sails or rigging and with a burned out hull, but put anchor to the ship anyway. Mariel Gullwhacker, Dandin, Tarquin Longleap Woodsorrel, and Durry Quill took it on their journey to Terramort for vengeance against Gabool. It was rammed by the Seatalon and, due to its already fire weakened wood, cracked in half and sank.
