Clyde Heffley was Greg Heffley's great-uncle who only appears in the Diary of a Wimpy Kid online book. He was replaced by Arthur Heffley in the book series, more specifically Diary of a Wimpy Kid: The Ugly Truth. Clyde does not appear to say any words but mutters noises like "Muurp" "Ruup?". This leaves Greg unsure whether Clyde is trying to say something or is making noises. Clyde stayed with the Heffley family for two days on Thanksgiving.
