Tillman is all black with a small white tuft of fur under his chin

Let's call Tillman a Ninja. He's wearing all black, after all. He's the sort of ninja who sneaks up on you while purring loudly, whose best attack is asking for attention, and who can perform the most amazing acrobatics in the course of his ninja work. Tillman's comrades are Levi, Caramel, and Mitty. He'll be happy to sneak into your home and heart solo, or take one of them along with him.
