Doomsday devices

Description
Doomsday Devices are several creations by Professor Farnsworth who is always looking for opportunities to use them. He used one which imploded creating a black hole which sucked in the cronotons. The Planet Express building has at least two storage areas for these devices. Farnsworth's favourite was the Spheroboom, until it was used and therefore destroyed.
