Nose-pronged device

The nose-pronged device is a device that is wired to two nose prongs. In 3012, Farnsworth used it to detect the pheromones of a giant male butterfly which Fry had been sprayed with.

In June 2012, Countdown to Futurama introduced the nose-pronged device through a design (released on June 4) and revealed some information about it - such as the fact that Futurama writer Michael Rowe - who wrote "The Butterjunk Effect" - "saw [it] as sort of a portable Smell-O-Scope" - through the fifth Futurama podcast (released on 5 June).
