We can assume that a larger snail moves faster simply by nature of being bigger. If we assume the snail's movement speed scales linearly with its size we can estimate its speed.
In the image he is twice as tall as the buildings which appear to be about 4 stories tall. 14 feet per story, times 8 = 112 feet. A snail is about 1.5 inches tall.
112 feet is 1344 inches. Divided by snail height, this snail appears to be about 900 times larger than normal.
Humans sprint at about 14 mph. A normal snail moves at 0.03 mph. Multiply that by 900 and our giant snail clocks in at 27 mph! Better find a car if you don't want to drown in snail mucus.
Fortunately, snail speed doesn‘t scale linearly with size, as the relativ slowing down of oxygen diffusion into the cells would shut down metabolic processes in the snail and lead to its asphyxiation.
I remember reading once that the human skeleton couldn't possibly support a 50-foot giant. Or even a 10-foot giant. The world's tallest people have all kinds of skeletal issues. The tallest man in recorded history, Robert Wadlow 8 ft 11.1 in (2.72 m), had to wear leg braces because his leg bones were so brittle. Also, he couldn't feel anything in his lower legs and feet because his nerves down there just didn't have the energy to make it to his brain.
I haven't seen that in probably close to 30 years, but the melodrama of that scene has always stuck with me.
Can't apply normal physics to Kaiju. They'd all collapse. Mass increases faster than height and their bones/shells/exoskeletons would break.
You know who that actor also was?
His name is Deep Roy and he actually has quite the number of IMBD credits. Lots of suit work like Warwick Davis. In fact, both of them were in Return of the Jedi. Warwick Davis was Wikkit the Ewok and Deep Roy was Droopy Mccool, the big pink guy who played some sort of horn in the Max Reebo band.
The giant snails tried their invasion in the middle ages, but were fought off by knights. All that's left of them is some doodles in the margins of medieval manuscripts.
Point of contention: Toho has only ever made good monster movies. This includes the bad ones.
I still watch and enjoy them exactly for what they are, but I think we're plugging our ears and closing out eyes if we can't recognize Raids Again and Son of Godzilla for what they are. I know people have vastly different rankings when it comes to these things, but those two in particular you essentially need to be a die hard (as you and I appear to be) to want to watch multiple times.
I shall gently perambulate in some direction other than directly towards it... unless I'm feeling feisty, and wanna try to ride that like a bad cowboy!? 🤠
