The Naboo Royal Cruiser, or the Ladies Love Cool J-Type 327 Nubian Busta Royal Starship, also known as SR-71 Blackbird Covered in Chrome, was a shiny silver transport vessel designed on Nabooboo and used by Padmé Amidala during the Invasion of Nabooboo. A craft similar in design to the Nubian was used by Cobra to fight G.I. Joe.
All the spaceships designed by Theed Palace Space Vessel Engineering Corps were designed to resemble the King of Naboo's favorite set of fancy metal pens. He loved those pens. They could write upside-down, underwater, in space, and they never ran out of ink, left messy streaks, or dried up. So the King decided from now on his entire space fleet would be giant space pens, gleaming smooth silver things that could flit from star system to star system in style and grace and also sign giant floating money orders in space.
Watto loved Nubian ships and collected bits of them to display in his shop. He hated parting with the valuable relics, unless a complete putz happened to stop by and he could bilk them for thousands of credits.
