Face is not riggable when ripping. [WarioWare: Move It]

[Nathbusia]

Now, in WarioWare: Move It, there's a microgame called "De-Stocking". Now, I really love how the models looked in this microgame, so I wanted to rip it.
But there is one little problem...
In the game, the NPC's face (like Jaw, teeth, lips, etc.) is fully rigged. Like so:

However, when ripping the model itself in Switch Toolbox (or such). Most of the faces are not rigged. Only leaving the eyeballs, and the forehead to be kept rigged. Like this:

Yeah... That's the problem. This doesn't affect her, but it affects anyone else in this Microgame (Yes, that also includes Julius Caesar). Mostly, I believe it is the files that the model came from (which being a .fmdb file than... whatever you guys are used to in Switch Toolbox).

Other than that, it is coming to Models Resources, but without the face rigged. Until then, is there any way to bypass or fix this mess?
Yeah, thanks again.

If anything, they might be controlled via Morph Targets/Shape Keys. Not sure if that's the case or not, but I'm just speculating.

Hmm... I'm not so sure if that is the case.
Because when I rip it and then import it into Blender, the models don't have any Morph Targets/Shape Keys built on them...
Unless there's something I'm missing out...
