Wally Darling used to be so Joyful and Happy, but ever since an incident with Home( A character of the neighborhood, who is Wally's home). But now, Wally's usual colorful self is turned into a colorless grey puppet, as he's always gloomy, and learning new things he didn't use to do, such as sleeping, eating (but a bit sloppy and messy), and other stuff a human would do. And anything he touches turns grey, except living things, and people. And live with Barnaby, since he's locked out, always sad.
