Theoretically...
Message:There are more eyes able to see us, since trunks don't see anything. Take THAT, Trick-Question-Tom!
Unless Tom would like to clarify all the parts of the riddle that are missing if one were to try to actually parse out things like numbers, including, do the elephants that don't have riders facing north have rider facing south? Every other elephant, so is that two or three riders facing north? MAY have a parrot? That's an undefined variable, not to mention that if the parrots are pacing, then there's a likely a varying amount of parrots facing west at any one moment... Plus, we're west, with elephants facing south and riders facing north, so, right now the only thing able to see us are parrots pacing westwards on varied shoulders.
But I stick with my initial answer. More eyes that can see us since trunks don't see.
Don't forget, Bjorn von Bjornsen is Clever.
And if all else fails he'll just go flaming-claw bear and eat Tom. *winky*
