P 133 of the Predator: Visser Three orders the Animorphs taken back to a holding cell and orders the guard tripled.
P 138 of The Predator: The door to the Animorphs' holding cell opens, and they see three Hork-Bajir in gold uniforms (sent by Visser One) and four red uniformed Hork-Bajir (the guards sent by Visser Three) unconscious or dead.
Since Visser Three had tripled the guard, that means that the original guard compliment consisted of 1 and 1/3 Hork-Bajir! What good is 1/3 of a Hork-Bajir?
