Giant Robot! 

I built Giant Robot in Muttsworld's survival server before the big reset. He's based on one of Hollywood's great character actors, Robby the Robot.  The light in his chest console oscillates Cylon/Knight Rider fashion.  There's a lovely garden in his posterior cavity, four water elevators in his head, and a Piston Parkour platform game in his right leg.

The observation platform for Giant Robot is a flying saucer with rotating lights (using a minecart on a track with detector rail to trigger the lights).  El Cad visits in the foreground.
