This is my boy Bob, a Sumatran water monitor, mildly venomous, super curious, and loves people food more than an indoor lab. First pic is shortly after I got him, slightly larger than a hatchling.
Next pic is after a year to a year and a half.
He loves the pool (water monitor) and roaming the back yard...one evening he wandered under the deck, and I instantly thought, "oh shit, this is gonna be fun prying his stubborn ass out from under there". 3 minutes later I hear a squeel that sent chills up my spine...and then out comes Bob proud as can be working a rabbit down his throat.
Now he's around 7 feet long and lives with my buddy in Florida. Had to move him since I needed room for taxidermy. I get to see him every year, and he recognises me and gets excited, follows me around my buddy's yard until he notices the Koi pond and decides to eat a few hundred bucks in goldfish.
