If you had to eat sticks all day with half your front teeth missing, you'd probably pull this expression, too!
You might be wondering why a herbivorous gorilla needs big sharp teeth just for eating plants. Gorillas have massive appetites and can chew their way through vast quantities of shoots and stems. They need large teeth to rip the bark from the foliage before munching the sweet treats within.
