5 minutes earlier.
The new robotic teacher was smiling vacantly with its glowing red eyes, black bobcut and straight across bangs. It still wore the teacher uniform of brown tights, a brown skirt, brown open toed shoes, and a white blouse with a brown cardigan.
"Ms. Franco?" One of the identical teachers said.
The robot that had been Ms. Franco turned its frozen face with a speaker in place of its mouth, its deep dark burgandy red lips forming the frame of the round speaker.
"INEFFICIENT TEACHER. GOOD RAW MATERIAL. PROCESSING." It says as its eyes flash and the questioning teacher freezes and in the palm of the converted robot another bangs with bobcut style helmet forms and is placed on the frozen teacher. The teachers panic but soon all are frozen and helmets are placed on each and their bodies and clothes are replaced with synthetics and made truely identical.
Their new artificial hive mind forms a plan and they march out.
The mothers prepared themselves but did not see the doors open behind them as rows of robo teachers marched out.
The Robo teacher got first strike and the back row of mothers didn't move fast enough when the PTA helmets slid over their heads. Soon the army of mother's was scattering to regroup as the others struggled with updo snapped helmets and their hose turned into black tights as their bodies became maniquinn like.
The new mother units grabbed the daughters for robotic transformation.
