The Fume Emitting Camera was seen in "Malled". The gadget appears to be a slightly elongated photographic camera with a capture lens on the right side of it, and a nozzle on the left side that is subtly disguised as a decorative rabbit graphic. When the trigger button on the top of the camera is pushed, the nozzle of the camera ejects a purple gas in front of it. The only effects of the gas appears to be respiratory irritation, causing coughing and eye irritation (though the unintended targets were protected with the use of goggles), and the gas itself dissipates within seconds.
This gadget made its first and only appearance in the episode "Malled". Alex originally used the camera in order to get rid of a horde of mice, but inadvertently found some of Simon Tucker's henchmen from within the same area.
