Instructions
Move right and left in between the gorilla's smashing fists. Stay as close to his mouth as possible to avoid being pummeled.
Jump and grab on to one of the gorilla's eyebrows when he stoops down.
Release your grip on his eyebrow when his mouth opens and grab on to one of his exposed teeth; the tooth will be pulled out.
Repeat the process in Steps 1, 2 and 3; you will defeat the gorilla on the third tooth pull.
