Colin is the antagonist in Don't Hug Me I'm Scared 4. He takes the puppets to the Digital World and teaches them about it. According to him, the only things you can do in the Digital World are digital dancing, digital styling, and graphing. He can tell the time, print pictures, count to 50 in the blink of an eye, and search for anything you need. He refers himself as a "clever smart boy" a "computery guy," and a "clevery guy". He also states that he is made out of buttons and wires. He is voiced by Joe Pelling. He dislikes the Red Guy the most. He is rude as he interrupts Gilbert the Globe and ignores the red guys questions.
