Hello, again! I recently watched a couple of video to prove Mangle's gender. It has been proven Mangle is a girl. One, SHE IS IN LADY'S NIGHT! If you look at the Mangle, she is wearing lipstick. Some people say that, the children put on the lipstick, but unless the children have a magic power to put on 3 dimensional lipstick, IT'S ON THERE AND IT'S STAYN'.
(Sorry If I seemed excited in the last sentence.... I was XD)
One more thing the phone guy lies. I know shocker. He has lost track of gender and calls EVERYONE he.
