This is now the problem with the digital age - anything can be "doctored" be it a photo or even a video because of the available software. I remember in the advent of the photoshop, my husband would be tinkering with the Adobe software and come up with interesting photos. One of those was his gift to our former colleague who is obese. My husband placed the head of that colleague on a sexy body. Since photoshop was not a byword at that time, that picture was a blockbuster. So when it comes to unusual photographs or even videos, they are not that credible anymore.
As are the figurines (and vehicles) in the snake pic. I don't know about the tortoise. The vid started with pics of The Worlds Biggest Pimple, so I stopped watching.
