#2005s

Thank you! If you plan to replace the original beak covering with a rigid material, you'll need to be careful to make sure that none of the moving parts restrict each other or you'll start breaking pieces. I happen to have an '05 with no beak covering handy, so here's a photo reference!

The corners of the beak (3 and 4) move up and down separately from the rest of the mouth, and the upper (1) and lower (2) beak can move separately from each other.

Additionally, the upper beak (1) needs to be able to move at an angle up towards the eyes, and the lower beak (2) needs to be able to recess into the faceplate. There's a small gap for it to move through but I think any sculpting would need to be very thin.
