This is Monster. The second picture is where you can see the spot on his hip/tail. He wouldn’t let me take pictures of him, like the other two in that tank so I didn’t take as many. Will try later.
He’s my favourite one for some reason. And I technically got him for free because he has six toes on her back foot, when they’re only supposed to have five. I told the guy they were inbred and he refunded my money. Not sure if that actually makes him inbred, but it was enough to convince the dude.
