With the death of Chief Sharptusk Thornmantle, "Squealer", now known as Chief Squealer Thornmantle, now leads the tribe. Having killed Greatmother Hawkwind, he now hides west of Camp Narache in the destroyed exit now called Thornmantle's Hideout.
Squealer's name may have originated from the boar, "Squealer", in the novel "Animal Farm" by George Orwell.
