I mean it'd make life a bit tricky what with boobs being kinda not like the surface we are used to.

Hey actually i remember reading that if you expanded a cueball to the size of planet earth, you'd have way way bigger trenches and mountain ranges etc. So maybe loads of wobbly mtn ranges and trenches with the nipple being a sorta massive mt olympus but bigger with a plateau at the top.

Yeah it would be weird and I am actually happy with the earth being, well, earth.
