Kara just goes with the flow as the robonapper tries to shove him inside the trash can. He was surprised as it lifted him, as he probably weights more than the trash can and the robotic parts inside. It lifted Kara upside down and showed him inside from the top, but only managed to get his head and part of his shoulders inside before his... physical wellbeing got in the way. The robotic arm lifted him up and down, trying to pump the over flowing flesh, which was just undeveloped muscle, just wait till Kara's diet begins to work, I tell you. Kara doesn't resist much, the robo-arm has pretty sturdy grip on him so it's not like he is in immediate danger and this isn't first time someone throws him inside trash can. The grip isn't painful either, so maybe this is new device to punish tardy students coming late to school. Though it seems slightly childish to shove someone in trash can. At least this time the trash can is empty and surprisingly clean for trash can.
