Sketch D. Rawing is a crudely drawn stickfigure. He strangely has a brown glow omitting from him all the time.
Sketch, can't talk. He can make random sounds, like all Skrawings. He is stubborn, confusing but at the same time, helpful. In Game Freak 2, you get a "Skrawing Translator", which translates all of the random sounds made by Sketch, and his species (although unseen), into English (or whatever language you're playing the game in).
“Hi everybody! I am Sketch, one of the most courageous Skrawings. I have come from my lovely town of Sketchville, in order of the king to help you defeat this... BOX fellow? Oh HAX! Sorry!”
