The polar bear ice tray has a lid at the end that you close so that you won't spill water on the way to the freezer like you usually do, it also makes it easier to get the ice out, no longer do you have to carefully twist the ice tray back and forth hoping that a cube doesn't fall to the ground. Just bash the polar bear over the counter, on the fridge, or on your dog, and the ice cubes are free and ready to be poured out of the opening and into your delicous drink.
