We don't know, it's not confirmed, invalid question

What I meant by that is who do you think did the bite of 87.

That's what I think.

Tbh the whole "mangle did the bite" thing is kind of ridiculous considering it has no base other than "mangles jumpscare kinda maybe looks like the bite" and "she kinda in disrepair"

OK.

It was the the scariest animatronic ever

Balloon Boy

Idk probably Mangle

Probs mangle idk, i can see toy chica ONLY for her voice lines in ucn but its probs not her

I just said only for the voice lines, i also said i really dont think its her

I think it was Toy Chica. If you play UCN, one of her lines is "Where's my beak? Lodged in your forehead of course.", but I only believe this because of her voice line.
