Where is location of Bow guardian / knight guardian sprite?

[UpsGo]

I just want to know where is the sprite of bow guardian / knight guardian? (I guess it's the same sprite with castle guardian)
because I can't find anything on sprite monster.
Is it the same case for emperium ? because 3D?

Yes they are 3D objects same as emperium, you can't find any sprite of them.

yC is right, but I would add, that those 3D models are stored in
data/model/3dmob/

If you are familiar with 3D modelling and tools, it might be possible to edit those files.
