Nozzle was the representative of the side of Sofa King in Royal Crown Coalition. He originally wanted to leave the coalition after the croaking and subsequent uncroaking of the Jetstone troops in the tunnels under Gobwin Knob. Prince Ansom persuaded him to stay with his attack on the walls.
He was shocked and crapped by a group of Golems led by Sizemore Rockwell during the siege of Gobwin Knob and has not been seen since. With the eruption of the mountain, and with most of the sides involved reporting complete casualties, he is presumed killed in action.
