The Urpney Spaceship is a huge vessel that only appeared in The Jolly Bird. It has the capabilities of carrying the entire Urpney army, has a giant screen for instructing the Urpneys, a hover engine as well as a thrust engine. It is flown by Urpgor, though due to it's size, it takes up a lot of fuel, and so ends up it only hovering for a few seconds. Even when installing a huge pedal powered helicopter propeller and two sets of bell rope powered ornithopter wings. Urpgor then instructs Blob and his men to find a mineral that would help to power it ten times, only to find that it only lasts for around ten seconds before crashing again.
