The means by which the potato beings of Narpelipoy make their way from place to place across the surface of their home world. Most often the ships will be wind blown, and thus the travellers - many thousands of whom might occupy the structures at any given time - have no real control over where they'll be taken. During sporial periods, however, the ships respond to some unknown and irresistible force, which propels them upwards and outwards through the nepulmium layers of the planet and off into the endless reaches of space. These periodic migrations of the sporing ships must account for the widespread populations of potato beings found throughout the Darpoi nebula.
