3 & 4 are curious but shy twin stitchpunks. They are unable to speak, using flickering lights to communicate with each other, but when they need to explain things to someone else, their eyes turn into film projectors. They instinctively run and hide at the sight of danger. Both wear hoods. After the Scientist created them, they playfully romped around his workshop and read all of his books. It is possible that they are made from gardening gloves.
