The Astratraz is a grey space craft with a single yellow window on the front. It has a round structure with lines running across it and has two fin-like protrusions ticking upwards on either side of it.
While Astratraz was being used to transport the criminal Puppets to a prison planet, its prisoners escaped from their cells and took over the ship. Teleported onto the Astratraz by the Ring of Eternity, Amy Rose and Tekno the Canary were taken prisoners by the Puppets. Faking loyalty to the Puppets, Tekno took the Astratraz to Planet Terminus for the Puppets to invade. Upon attempting to invading the planet though, the Puppets were eaten by the giant termites infesting the planet. With no prisoners in tow, the crew of the Astratraz contacted a base for a ride back home.
