So I used to just be the lab rat, gonna be adopted out once I found a good home. But now I'm gonna stay here until the end of time. Me and Brayden, my lovely Halloween Deaver. Ain't he scary? I'm pretty scary too, ain't I. Mutant and Yurbley. For now. I've been a lot of things. I liked being a Poogle. But that was short-lived.
