SCUMM/HE: Fatty Bear's teeth are green (fbear)

[Thunderforge]

Whenever Fatty Bear is facing the camera and starts talking, his teeth start alternating between white and green. They should consistently be white (or some other appropriate color perhaps).

Reproduction steps

1. Start a new game
2. As soon as Fatty Bear gets off the bed and normal gameplay begins, Fatty Bear will start talking and his teeth will alternate between white and green.

This also happens at any other part of the game where Fatty Bear is facing the camera (e.g. clicking on him to trigger dialogue).

Versions Tested

• Steam release of Fatty Bear's Birthday Surprise
• ScummVM 2.1.0 (shipped with Steam release)
