Jimmy was a boy who's birthday was celabrated in his debut episode "Just Set up the chairs" . He was a rude ,ungrateful, boy who was probably 7 or 8. He had ginger hair and a yellow T-Shirt. He made a Cameo in brain eraser, too. In brain eraser when mordecai skips and rigby were in mordecai's memory trying to erase naked pops, they summon a bouncy castle to break the fall. Out of that castle came Jimmy along with some other Kids who attended his birthday.
