Shang-Tu

Iris Wildthyme, Tom, and Panda visited Xanadu and encountered Kubla Khan, who gave Iris a hookah. (PROSE: Iris Wildthyme y Señor Cientocinco contra Los Monstruos del Fiesta)

Behind the scenes
In the real world, Xanadu is another name for Shangdu, which was (in retrospect) archaically referred to as Shang-Tu in TV: Marco Polo.
