Events of TBoGT
Joni works with Luis as part of the "Club Management" side-missions. Luis keeps in contact with her via headset whilst scanning the dance floor from the security room for trouble, telling Luis to check out certain areas where she sees disturbances.
Occasionally, Joni will call Luis to her office and offer Luis sexual favors such as a sexual dance, a blowjob or sex. Sometimes she will scold Luis if the player had sex with other women.
- Joni constantly teases Luis about his penis size. At the beginning of the club management missions, she will make comments such as "you have a great body L, shame about the little guy!", "Do steroids make your balls shrink or were they always like that?", and "So you WERE overcompensating."
- Just like with any other club employee, killing Joni will cause her to respawn the next time Luis returns to Maisonette 9.
- If the player purchases Episodes from Liberty City (disc version), it comes with a poster of Joni on one side, and a map of Liberty City on the other.
- Joni's appearance differs between her artwork and her appearance in the game, as her artwork depicts her with thinner lips and differently shaped eyes.
- Joni bears a resemblance to the late star Joan "Chyna" Laurer.
