Info from Licensor: "At the LA Zoo with my girlfriend, we were passing by the gorilla pen when we saw one gorilla looking perturbed and following the other one around wherever it went. We thought it wanted to be friends however after a while of this, they went behind the trees and started brawling. Only to come out from behind and carry the fight to the front of the pen as well. Both gorillas had blankets that they were dragging around, we suspect it was a fight over these blankets and the territorial nature of their possessions."
