Evacuation at the zoo

Last friday I had to evacuate the zoo because a cassowary bird escaped from its pen and was running rampant!  Apparently they tranked it and the threat was over,  but I believe this to be a cover up for what actually happened.  Yes the bird escaped, but because my animal anatomy teacher was missing at the time im pretty positive he overcame the the beast himself, mounted it and road it back into his pin.  See picture below for how it went down.  Side note wasn't sure what a cassowary looked like at the time, but it had to have been something bad ass if they had to clear out the entire zoo!  So heres my interpretation of the event.
