Loudmouth is a Thunderdrum who lives nearby Bork's Cave.
Loudmouth first encountered the Dragon Riders when they were searching for a map in Bork's Cave. The angry Thunderdrum attacked them, shooting its sonic blasts everywhere. Fishlegs distracted him with a Thunderdrum call, while Hiccup and Toothless entered the cave to look for the map. Later on, Hiccup and Toothless returned and Astrid and Fishlegs fired at Loudmouth and managed to chase him off.
