Nightmare Balloon Boy

Nightmare Balloon Boy is the nightmarish version of Balloon Boy and is an antagonist in Five Nights at Freddy's 4:Halloween Edition. He is one of the few new Nightmare animatronics alongside Nightmare Mangle and Nightmarionne. He's featured in his own minigame known as Fun with Balloon Boy, and thus functions similarly to Plushtrap.

Appearance
Nightmare Balloon Boy appears similar to the original BB, except with a more nightmarish design. This includes large teeth inside of his large mouth (similar to Nightmare Chica), long claw-like fingers, and more sinister looking eyes. He has a red nose and cheeks instead of orange ones. He also has a red and purple striped hat and shirt, instead of his usual red and blue stripes. Interestingly, Nightmare Balloon Boy appears to be in a perfect and completely undamaged shape.

Locations
Nightmare Balloon Boy only exists in the Fun With Balloon Boy minigame, which functions almost exactly like Fun With Plushtrap.

Trivia

 * Both Nightmare Balloon Boy and Plushtrap are the only Nightmare animatronics whose hands do not expose their inner endoskeleton.
 * However, Nightmare Balloon Boy is the only Nightmare animatronic whose claws do not have any metal exposed.
 * This is the second version of Balloon Boy with a jumpscare, after Phantom BB.
 * Nightmare Balloon Boy is one of the three nightmare animatronics to appear in both the Standard and Halloween Editions, the other two being Nightmare Freddy and Nightmare Fredbear. This is because Fun with Balloon Boy can be selected and played via the Extra menu in both versions. It is important to note that Fun with Balloon Boy's inclusion in the Standard Edition is not meant to add anything to the game's lore.
 * In his jumpscare, Nightmare Balloon Boy's teeth visibly clip through one another. This is likely a mistake on Scott's part.
