Matthew Scott Reber is a puppeteer and a cousin of Logan and Lance. He appeared in Happy Halloween! as Jeff The Killer, and returned in Jeffy's Clone! to provide the voice of Scooter. He reprised this role almost two years later in Jeffy and Junior Skip School!, and after a few months of absence, re-reprised it in Jeffy's Scooter!, from which point on Scooter became a recurring character in the SML universe.
