Captain Murphy is the captain of Cecil Tunt's underwater laboratory and has missiles tipped with VX nerve gas. He was killed when he was crushed by an off-brand soda machine, "just like the gypsy woman said". The soda machine was branded "GOZ," a reference to Harry Goz who was the voice actor for Captain Murphy on Sealab 2021. His death is a reference to the Sealab 2021 episode "All That Jazz," in which Captain Murphy is trapped under a "Bebop Cola" machine.
