Brilliant characters! Great use of the Cars pieces and the you've designed the mouths to give them expression is excellent. Worrybot is worrying about where he left his detachable thumbs... Unhappybot is livid because the dishwasher is broken. Could the two be connected?
Worrybot has forgotten to remind his builder and his builder's friends to go over to Michael Rutherford's Decisive Action Game and put smileys on ALL of the Primal Scream Groups' MOC's! BTW, they are cute! :)
