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

Something called the “square cube” law. Imagine Godzilla was humanoid instead of reptilian, and 6 feet is a reasonable height for an adult man. If you double a person’s height while keeping the proportions of their body the same, the cross sectional area of the leg bones of a 12 foot tall “giant human” will be 4 times the area of those of a normal person (square of twice the height), while their mass will be 8 times that of a normal human (cube of twice the height), so the stress (force divided by area) on their leg bones will be double that on the leg bones of a normal human.
How big is Godzilla? From the lyrics of the theme song of the Saturday morning cartoon “Godzilla Power Hour”: “Up from the depths, 30 stories high”. Typically a story in a building is 10 feet (8 foot ceiling plus 2 feet of structure). That would make him 300 feet tall, or 50 times as tall as a person. His leg bones would have 2,500 times the area of a person’s (square of 50), but his weight would be 125,000 times that of a person (cube of 50), so the stress in his leg bones would be 50 times that of the stress in a person’s leg bones.
Even King Kong (from the cartoon’s theme song “10 times as big as a man”) would be supporting 1,000 times the weight of a human on leg bones with 100 times the area, for 10 times the stress.
