In december 2006, Shedletsky made a "Killbot" model. It's a flying ball that shoots rockets at you. He added it in 3 places: Timmy and the Killbots, Glass Houses, and Trouble in the Killbot Factory. The first two are easily accessible on roblox, but the third one is lost. Quote from a page about Killbots in the ROBLOX fandom: Little is known about it's appearance in this level, except that the Killbots in this level were a violet color, and coded similarly to the January 25, 2007 model. The level's appearance itself was similar to Timmy and the Killbots.
