What about a creature that has a limited height and width that is infinitely long and constantly traverses the landscape.
I'm imagining something like a giant centipede or worm where there's huge arches between each supporting foot of the creature. Large enough that if it happened to come across a building (or maybe even something larger like a city) it could just step over it. The legs could follow the exact same route through the air as they move into position. And each 'foot' would land in the exact same spot that the previous 'foot' occupied. Naturally the land underneath would become super-compressed over time. Perhaps people could find a way to divert the path of a section of this creature to use the land crushed by its feet as a really flat and solid foundation for building?
Anyways the creature would be infinitely long and each section would be supported by its own independent legs and feet.
I'm not sure about nourishment though. Maybe a symbiotic relationship with creatures that live on it. 731
Fungi, animals and even plants could live on something this large that is always predictable. It follows the same path with the same timings. Perhaps it moves at the same rate as day and night? This really depends on the exact workings of the day/night system. But if some sections would be in day while other sections are in night, then you could maybe have portions of this creature that are constantly in daylight and portions that are constantly in darkness. This could lead to variations in different sections of the creature and the symbiotic creatures that live with it.
There's a lot of things you could do with this sort of creature as it's path could be very random meaning there'd be huge sections of land without any worm and huge sections of land that might be governed by the nearby worm paths. It'd be large enough in height that it's not insignificant and is difficulty to damage. How exactly would it recover from damage though? Perhaps some sort or merge with other pieces of the worm. That's up to you.
I just like that in an infinite world there's a creature equally unending that affects almost every part of this infinity, helping form the civilizations and creatures that live in all areas of that infinite world. 258
