I think the BB dangler was actually based on an edit of Withered BB. Notice the endo hand, and the stick? His "stick" is actually supposed to be a broken "balloons" sign.
The reason why the old Balloon Boy dangler look odd is because it's based off a fan edit of "Withered Balloon Boy". They fixed it so that they don't get into trouble with anyone.
The bb danger is actually stolen from a fan design, or they didn't know if it was official or not, remember that withered bb by fazboggle that used to be used as a "fnaf 3 leak"?
I have a lot of backpack hangers. I honestly don't mind them. Are they my favorite? no. But they're not really that far off, stylistically, from Funko Pops. Yet everyone acts like they're horrible.
I used to have a FNaF backpack lol, it was the perfect size, I'm kind of sad I couldn't keep it. It had the FNaF 1 crew with some pictures of Puppet next to one of the zippers.
