JJ is one of the main antagonists in Five Golden Nights at Freddy's 2. She is a hallucination that hides under the desk inside The Office.
JJ is a female balloon vendor that has a purple nose and eyelids, pink cheeks and iris, a purple and blue cap with a magenta sphere on it. It is unknown if JJ is really a female, but in FNaF World, JJ does in fact have tall standing eyelashes. She doesn't seem to glow white pupils.
JJ only appears in The Office as she can only rise up above under the desk.
JJ disables the use of the Bonnie mask, until she leaves the office
