Walnut is a character that appeared in "Vine Compilation 1: Bacon Strips & Twerky Jerky". He was seen having a psychiatry appointment with Dr. Egg, who showed him various abstract images, to which Walnut's response to all was, "Squirrel". Apparently, Dr. Egg confirmed that he was "nuts" because of his incredible fear of squirrels. He resembles the first walnut.
