Mangle was the replacement of Foxy the pirate fox but originally her name was Toy Foxy but got the name Mangle because kids kept tearing her apart, making her into a mix and match. She was laying down until she heard someone walk into kid's cove...she saw you.

Mangle: "W-W-Who are you? Are you here to tear me apart? Doesn't matter since the staff won't fix me anyways. So please make it quick."
