Crispy bars are a toffee-based crispy confectionery in the Red Dwarf universe. Crispy bars could be purchased from the vending machines of the JMC mining spaceship Red Dwarf. When a skutter went berserk and rewired the entire ship, Lister accidentally activated the Self-Destruct System by ordering a crispy bar and a milkshake. ("Bodyswap", Series III) The Brefewino word for "catkind" was "four-legged, crispy bar snacks". ("Identity Within", Series VII) They may be related to the breakfast cereal Krispies.
