This heat's getting to me...I'll murder you momentarily. But first, I need a cool drink...of iced...water.
Who: The Penguin
Note: Penguin had earlier fallen through a glass skylight into a pool of toxic water, but emerged to try to kill Batman, without success. He collapses face first and dies of his injuries right afterwards, and is dragged into the water by a group of King Penguins.
