It's funny how I was all "people keep underestimating their large fursonas' weights because they're not factoring in that linear height changes ≈ cubic weight changes" for years before actually doing the math and realising I was lowballing my own fursona's weight by 5×.
"how the hell is your fursona 650kg, they're not even 3m tall" "look, if you make someone 1.5× taller, 1.5×1.5×1.5="
It turns out they aren't! 3,050kg.
There's three whole dimensions for you to be big in. Possibly more. Occasionally less.
