Mecha-Gym-Teacher

You enter the Hall of Gymnasia to find a large group of horrified freshman hiding below the bleachers.

Before you can ask them what happened, the Mecha-Gym-Teacher jumps out from behind a bush. (Yes, there IS a BUSH in the GYM, and no, I do NOT know how a 153-foot robot/athletics-educator hybrid can hide behind it, but he did.)

Your time is short, he is not, what is your plan?
