Modest Mouse has debuted Heath Ledger’s whimsical-yet-dark video for the song “King Rat," the AP reports. In the video, which takes aim at illegal whale hunts, Dr Seuss-like animated whales and dolphins go on a bloody hunt for humans, notes Vanity Fair. Watching it might require a little Dramamine, it adds. The video concludes with the message, “This began with our friend, a great defender of life, and was completed in his spirit.” (More Heath Ledger stories.)
