Forum:2nd Claptrap in Fyrestone

Has anyone figured out how to interact with the green claptrap in the rocks above and behind the weapons store in Fyrestone? It waves at you and says 'Over here' when you jump up on top of the roof but you cannot step onto the rocks to get close to it. As far as I can tell he isn't part of any of the missions or side quests. Did a programmer just add this to be cute?
