Chestnut is a recurring character in the Annoying Orange series.
He appeared in "X-Massacre #3: Nutcracking the Code". Orange annoyed him to the point that his head split open. He was suicidal, calling the hand to take him away.
He returned in "Dive Bomb!". When the teeter-tooter was ordered by Orange, he refuses to take offense ordering and demanding a apology to Orange, but he was launched to the sky by the box while standing on the teeter-totter. He appeared later on being back on the teeter-totter, but then Grapefruit went on there causing him to be launched up yet again. Starting near the end of the video, he was exploded by a TNT.
