Milky-Pink City was a city on an unknown planet. Six thousand robots were imported to serve tourists, but Intergalactic Tourism somehow stopped tourists from visiting there.

When the Tenth Doctor and Martha Jones went there, the robots fought to see who would take the Doctor's coat and who would get Martha a drink. Eventually the robots turned on them. The Doctor used Martha's iPod to play music. The robots were distracted and began to dance while the Doctor and Martha escaped. Martha thought this always happened when you tried to force people to have a good time. (PROSE: The Pirate Loop)
