This was an April Fools joke that I pulled this year. It is not a photo manipulation but was built entirely in a couple of 3D programs. I said that I had caught this thing while fishing in Maryland and that it was one of several mutations beginning to show up and was locally called a Sea Pig. I said that I had it living in my basement and didn't know what to do with it. I admitted it was just a joke after receiving several offers of help and one suggestion to "just eat it".
I would like to animate it but in a way that won't make it look fake. I was considering making it breathe and barely move and then filming my monitor as the animation played. I was wondering if anyone had tried this.
