B.Z's nail teddy bears. How did he get the nails, broken glass and sawdust inside the toys? Even with automation you still need to bring a significant number of workers, designers and managers in on this. Did none of them decide that this man was loopy enough that it was worth risking their job to preemptively call the police? Did no one realize that the obvious criminal charges that would be filed the moment someone found out (to say nothing of the civil suits)? For that matter, why did he do it? Did he not realize that this would financially ruin his company and drag its name so far into the mud that it would never see daylight?
The nails and glass were deliberate, but not just For the Evulz. The bears are clearly supposed to make a bell-like noise when you shake them. B.Z.'s just so amoral that he decided the tinkly noise may as well be made out of nails and glass since they were cheaper than bells.
What was the point of the Super Dooper Looper at the climax?
The Patchmobile was behind Santa's Sleigh in the climax (Santa overtook them) right before the candy canes exploded. There was no way to turn around to catch Patch and Joe and they had to clear the explosion so they couldn't slow down, plus they had to get UNDERNEATH them to catch them. By doing a loop they cleared the explosion, and were in position to catch Patch and Joe as they fell.
