...
JJ is a different-colored counterpart of Balloon Boy with a currently unknown origin. She made her first appearance in Five Nights at Freddy's 2 as a minor hidden animatronic(That means that it is rare for people to see her in the game).
Physical Appearance
Though her model is exactly the same as her ordinary counterpart BB, she has blue cheeks and magenta eyes, a purple nose and eyelids, and the red stripes on her propeller beanie are instead bluish-purple as well as a button from on top being blue, with blue propellers and a yellowish-orange button. Her shirt also has the same pattern as her propeller beanie cap, with purple and blue stripes.
In Five Nights at Freddy's 2, her rosy cheeks are magenta instead of blue while her beanie button lacking a propeller is colored red than blue.
Personality
Little is specifically known about JJ's personality, save for the fact that she, judging by her laughter(She has the same laughter as Balloon Boy) heard in Ultimate Custom Night, is implied to be a cheerful sort of character.
Appearances
Five Nights at Freddy's 2: Occasionally, the player may encounter JJ hiding under the right side of the desk in The Office while looking directly at them. JJ does not appear to affect the player, neither attacking or jumpscaring them. She seems to simply disappear if the player checks the Monitor.

The challenges in which JJ is present are as follows:
