This is Shinigami, Haruka's Ball Python. He loves heating pads and sticking his tongue out at people when they're not looking. Or when he thinks they're not looking. He is the largest of Haru's reptiles, but he's a very sweet boy. He's really good about being held and is actually pretty lazy. The most likely place you'd find him in his enclosure would be just curled up in a pile in the corner, like a big sleepy piece of spaghetti.
Extra: His name, Shinigami, is a misnomer (an inaccurate name/title). It is Japanese for "Death God", but like most ball pythons, he's super docile. Haruka did this on purpose because they knew that it would dissuade most people from messing with him for fear of invoking his "wrath." I mean, most people know not to mess with a three-and-a-half foot long constrictor, but some people need that little extra deterrent to remind them, "Hey, keep your hands to yourself." Haruka also finds it sort of funny to watch people squirm when they hear his name and the explanation as to what it means, to be honest.
