hot take against macro furries but unfathomably large isn't actually all that large, humans are terrible at estimating scale once you get past like building-sizes
like let's say your fursona is as tall as from the earth to the moon, a mild one on the space-macro scale, reaching up and grabbing the moon is a common thing for that kinda art
If you could jog straight up how long do you think it'd take to cover than distance?
About 6 years non stopIf they were that tall, they'd have to contend with the earth and moon sticking to them like staticky party balloons
...I think I've seen that one somewhere.
