Moby Sick Quinn is struck with a moral dilemma when Abelard, a whale dying of asbestos-caused "whale cancer," begs Quinn to euthanize him. Environmentalists insist on saving his life, while a few people insist euthanasia is the best option. Dolphin Boy takes up the banner of Odontocetian Pride against the intrusion of the inferior Mysticetians, vowing to kill Abelard. Marco discovers that Abelard's cancer is delicious, and proceeds to eat it all out of him at the end of the episode, as a skinhead Dolphin Boy jumps onto him with a harpoon and Debbie DuPree chains herself to the swiftly sinking whale.
