The Darkness Pump is a mysterious device used by Concavia Light Works.


The Darkness Pump is a Concavian invention intended to provide sunlight to the underground world of Concavia. Logic be damned, it does this by sucking out the darkness from the air and somehow converting it into sunlight. Mickey Mouse marveled at this device when Wing Ding showed it to him during his 1954 visit to Concavia.

Behind the scenes

The Darkness Pump appears in the 1954 story A Fatal Occupation.
