What happens if you suddenly become 60 m tall? You are 35 times taller, but your body scales in three dimensions. So, your mass explodes to roughly 40,000 times heavy.
Now, your own weight becomes the enemy. You instantly collapse and break because your legs are too thin and your base is too small for that weight. If you want to stand, you need truck- sized feet and pillar thick legs.
You try to walk and it turns violent. Each step hits like an earthquake and normal bone would splinter from the impact. To move at this scale, you need a super dense skeleton.
Then you start to faint because moving this body burns insane energy. Your lungs cannot exchange enough oxygen and your heart cannot push blood 60 m up to your brain. To stay conscious, you need massive calorie intake, much larger lungs, and a gigantic heart with extra pumping power.
And with all that energy, you are basically a walking oven. Heat trapped deep in muscle and organs. So you cannot keep normal skin anymore.
You lose most of it. So exposed muscle can vent heat directly. Steam rolling off your body.
Does that look familiar now?
