Kill Bill seems to be a Springtrap version of an Angry Bird as he has torn eye sockets, rectangular teeth, a human like eye, a stitched mouth, stitched eyelids, and alsi the same color scheme. Interestingly enough, both Springtrap and Kill Bill are both hybrids, however, they are both different hybrids. Springtrap is a hybrid for being a wearable animatronic while Kill Bill is a hybrid for being both a pig animatronic and bird animatronic. You can tell he is half pig animatronic because he has a pig animatronic ear on his right side of his head.
- As said by the creator, Kill Bill was a reason he cancelled Five Nights at Piggy's 4.
