I don't agree that they are not unlike ...
The common argument from Patty cakes, when some anatomical feature not consistent with known morphology is pointed out, is that since we don't have a Bigfoot body - how do we know feature XYZ is not unique to Bigfoot/Patty ?
You missed the point about the wrinkles ..
You seem to be arguing that since Bill Munns cannot identify any wrinkles that he feels are consistent with suit technology, it makes a case for real animal vs suit ..
It does not - because a valid counter argument to that - would be that any animal exhibiting wrinkles like those found in a suit, could possibly be a mime in a suit .
But that is not a good argument - because in spite of the wrinkles - we have much more valid evidence that any given Shar Pei is not a suit.
By the same token, the preponderance of evidence ( or lack thereof ) would lead most rational people to conclude Patty is a mime in a suit, all arguments from personal incredulity notwithstanding ...
