Animatronics Help!

[ThePuppeteer]

Okay,
So there was an officially licensed 16` Talking Ted doll.

He says 6 phrases which are entirely too inappropriate to be talking about here..
Anyways!

I slit a hole in the back to get the unit that moves the mouth.
There are three parts.

- A speaker.
("RoHS TK-1213)

- A battery pack.
( it takes "AA SIZE 1.5V x 3 (R6/LR6) batteries. It has an on and off switch, and it is also manufactured by "RoHS". )

-A button which operates the mouth.

-The mouth.


I would like to reprogram it.
Can anyone help me do that?...
