Fair. A whale sized creature living on a planet with 1/100th gravity could work. The square/cube law starts doing weird things tho at that scale. Like, could you build a pressurized space ship that big, or would the walls have to but meters think?
The thickness of the walls is determined by pressure it's trying to contain, a city sized ship and human-sized space suit are trying to contain the same pressure.
That's largely determined by the planet itself though, if it's smaller or spinning faster, it's easier to get into space.
