I haven't seen any living beings in the bright city world, though I am sure they exist, as the city changes. It is a very colorful place, to the point of being gaudy, overwhelming stimulation.
It's as if the city is in a perpetual state of celebration. What kind of creatures would build these structures, and why do they move them?
In all the worlds my mind goes to this is the most unusual world/reality. Most realities have plants, animals, but no humans, no beings with intelligence. Why, I wonder.
