"I seldom use it myself, sir. It promotes rust." - Robby the Robot
Robby the Robot was a friendly robot first introduced in the 1956 science fiction film 'Forbidden Planet' and has appeared in various projects since.
Robby (wearing a hat) could be seen at the Inventors Convention which Randall Peltzer was attending prior to the gremlin invasion of Kingston Falls, standing behind Randall, who made a phone call home, and used another phone himself.
