Digby's old spaceship

 is a spaceship that, on the night of 31 December 1999, Nibbler's personal chauffeur &mdash; Digby &mdash; used to land Nibbler on the rooftop of Applied Cryogenics. Digby and Nibbler then went drinking at O'Grady's Pub, but Digby accidentally dropped the ship's keys in a gutter, so they had to take a cab back to their base on Vergon 6, where Digby's boss gave him a new ship. Digby then began going planet to planet looking for the old one.

In 3013, he was still looking. By using the old ship's key fob, he had constantly been emitting a deafening melody, which had destroyed a planet and was causing seisms on Earth. A musical response to the melody prompted him to land on Mount Shushmore, where he found Nibbler and the rest of the crew, as well as Nixon and Agnew. Fry helped him retrieve the old ship, which was still at Applied Cryogenics, although its cassette player had been stolen and its battery was dead, and he then flew away in it.
