Sammy first shot to fame in 2007 when his mum posted a picture of him trying to eat sand on Flickr.
The image quickly gained huge traction online and was used in a variety of hilarious ways.
Sammy reappeared again last year, aged eight, in a successful campaign to raise enough money for his dad Justin to have a kidney transplant.
And this is what he looks like in 2016.
Sammy’s dad, Justin, of Jacksonville in Florida, spent hours on dialysis every day for six years after his kidneys began to fail.
Initially, Sammy’s mum didn’t want to use the popularity of her son’s meme to fundraise but after changing her mind the family managed to raise more than $100,000.
Justin underwent a successful operation last August after a donor match was found.
