UCN[]
JJ was a customisable antagonist of Ultimate Custom Night. Similar to Balloon Boy, she attempts to sneak in through the right side vent. JJ sneaks into the Office if the protagonist fails to close the vent in time. She then hides under the desk, disabling the protagonist's door controls for a short time, lasting approximately 10 seconds before vanishing.
