The Captain Hook costume variants changed several times.
Captain Hook's mouth is closed, and his eyes are apart. This costume retired from most parks in 1999, save for Tokyo Disneyland, where it was retired in early 2001.
This version of Captain Hook is a closer match to his animated counterpart and has a slightly scary grin with his teeth showing up.
