So  tiamat and I are making up these techno music dog things. This is the bass system, her name is Subwoofer. :E She also does any of those "bow wow wow wow" sounds in dubstep and crap. She's got LED lights all over her that change to the music, as well as equalizer lights on her legs.
There's a strobing light in the back of her throat.
Her tail is like one of those LED alarm clocks with the stick that wags and spells out things. She can wag it really fast and spell stuff or make designs.

I dunno what she is made out of, but she and her counterpart Dubstep (Tim's character) hook up and make electronic music. :E
