George is a hungry guy with some blades mounted on his arms. To beat him, you need to stun him then shoot him in the head whilst stunned.
Use your Boner to shoot a light barrel when he is near. He will be knocked down. Then change to the Monocussioner and shoot him in the head as fast as you can. After about 3 hits George will grab a goat head and run off. Look for the only illuminated (red) building in the darkness, then ignite the goat to restore the light. Then get George to chase to to a barrel, stun him, shoot him.
He will eventually grab the goat again, repeat a few times then his mask will break and he will be taken by Fleming.
Grab the blue gem to get the Teether
, then walk out the door to finish the level
