Stupidity: Robin uses the high pressure water from the pump to neutralize the bear next to Batman (which is like 10 meters away from him and still the water jet is so strong that it pushes the 1000 pounds bear away and flips it on its back,), but does not use it to push away the other bear that is literally breathing on his face centimeters away from him. He has all the space and time to do that (especially after Batman's intervention). (00:50:30)

Stupidity: Belson wakes up Barbara and unlocks her chain only to try and give her an injection of sedative for the operation. Who would ever do that, instead of keeping her asleep and restrained?
