It also has an ability to hover through walls (in early glitchy versions) and can open doors. PewDie called it Mr. Sexybutt for having a sexy butt.
He first appeared on episode 1 of the SCP: Containment Breach playthrough. After months of not playing, PewDiePie played SCP again, after some updates. He got killed twice by Mr. Sexybutt on July 24th, 2013.
