Hule is a sometimes a bit shy but always happy rubber fox, around 5'8 tall, who loves tf'ing, flattening and stretching his rubber body, his favorite tfs are into vehicles, though his body has a limit in how much it can stretch, but that doesn't stop him from tf'ing into huge things, like trucks, planes or even houses.
He has a zipper in his back that lets him be worn as a rubber suit, and when that happens he can choose to have control over his own body or let the wearer control it, those blue circles in his hands are there so that if the person inside wants to use his own hands, instead of the huge ones the fox has, he can do so by taking out those pieces of his hands and push their owns through the holes.
He would love to try inflating his body with air like a balloon, but unfortunately the air always end up leaving his body through some small gaps in his zipper and in the holes in his hands, even if they are sealed with those blue circles.
