Spaceship Remotes were gelatinous lifeforms used by the Novrosk Spaceship in its search for power to restart its systems and take off.
The Remotes, nicknamed 'Blobs' by the Ninth Doctor, appeared as large, blue, glowing hemispheres, with one long electric blue tentacle on each side. Should a human being have been caught in these, they would have been quickly drained of energy and aged rapidly until reduced to a withered husk.
The energy gathered would be transmitted back to the ship itself, and would be used to power up its sytems. In addition to this, the Remotes possesed the ability to survive both in water and on land, and incredible strength, being able to break through a solid concrete wall at the research base.
