"Screampunk" is a portmanteau title of "scream" and "steampunk".
As Minireenas were not reskinned with Arctic Ballora, the Screampunk Event marked Minireena's first time to earn a skin (Clockwork Minireena), making her the first and (currently) only non-delivery side animatronic to be introduced with a custom skin.
The term for Aeronaut Toy Freddy's name, "Aeronaut", refers to travelers who ride in hot-air balloons and other flying air crafts.
Jetpack Balloon Boy was accidentally leaked by Illumix on their YouTube channel hours before he was released on the same day, however, the leak was quickly taken down.
As seen in the Workshop, Jetpack Balloon Boy is seen floating instead of being at normal ground level like all the other animatronics, it's unknown whether this feature is a bug or intentional.
