Cor. Someone's taken the Robosapien robot and merged it with an Elmo hand puppet to produce ElmoSapien, complete with over 200 custom sound effects to make the bot sound just like the real Elmo.
Well, the fictional puppet Elmo, obviously, but you know what I mean. Full instructions on how to make ElmoSapien are provided on the RobotsRule website, and it seems fairly easy. Better still, it's effectively a suit for your Robosapien, so doesn't mess the bot up if you want to transform him back in the future.
