Bomassa loves to eat, and it shows! I am told that he is the easier brother to train. When the gorillas are learning their routines, they get treats in return. For example the keepers might need for Bomassa to turn his ear towards them, which would be useful, for example, if they need to check for infection. If he turns the ear, he gets a bite of kiwi, one of his favorites. Apollo gets the same opportunity, but is less interested in food, so he is not making quite so much progress with his training.
