What do people mean when they say that a giant monster like Godzilla would “collapse under the weight of itself?”

Question

Wouldn’t a monster that big have extra large bones and muscles to support all that mass?

Answer 1

When you increase the size of something, its parts and properties don’t all scale the same. So it’s getting, say, twice as big, but only 1.8x as strong. At a certain point, the strength doesn’t increase enough to support its weight.
