The robot pounded heavily on the door, but it was a sliding door and not one that opened on its hinge, so HAHA stupid robot. Heiji wasn't sure how much time had passed, exactly, but the robot's struggles began to slow, most likely as the cold temperatures inside began to affect it. Slow, and then stop.

If they opened the freezer, they'd probably see the robot doing its best Jack Nicholson impression.

"...Well," said Heiji, switching his light back on, "Guess robots ain't like the cold much, either."
