Prettygrumpybear believes Toy Chica's beak is in (or part of) Mangle. Some others believe that Toy Chica is trying to build up Mangle (A.K.A Foxy 2.0 or Toy Foxy in their cases) But Prettygrumpybear is possibly right where she puts her beak but she also has a video where she found Toy Chica's eyeballs.
I could not find the video about the beak but the eyeballs I can find easily...so...sorry 'bout that and the short chapter again.
