"What I'd suggest, my lord, is we use one of our little surprises on it," Grima said.
He opened a door. Inside were numerous cages in which about a thousand little rodents were frothing at the mouth and gnawing at the bars.
"WHAT?! THAT's where all that incessant squealing was coming from? Who put those hamsters in here? I'll kill him!" the White Wizard bellowed at a needlessly loud volume.
"Um, well, uh, I... kind of brought them along," Grima admitted.
He suddenly found himself being thrown to the ceiling and back.
"What I was going to suggest was that you could release these rabid killer hamsters against the troll. I mean, no offense, Master, but that voice of yours, well, it's, um, kind of horri-"
"YES?" Saruman glared at Womtongue, staff pointed at his face.
"Never mind," Wormtongue whimpered. "Though we could just run over the troll or feed him to the Wargs. Perhaps you could use that staff of yours to perform some kind of mind trick on him so he does something ridiculous, too."
