Once you decrypt them, you need to know the file format.Even if you find the files, opening them in an editor would be useless because they can't be read. Most games now encrypt the files so you can't tamper with them.

If you're lucky, you can find the animation control data and add frames. Ultimately, somewhere in the game's data files, something somewhere tells the game "this is the image you use to draw the Druid and here is the data for each frame".
