What's up with Splatoon's textures?

Recently, I was playing around with the model of Callie from Splatoon, and I noticed some strange stuff in the textures.

Here, I'm using her funky dress as an example.



Of course, there's pretty clearly the three main maps you'd see in a Nintendo model:

 



The texture, the specular, and the normal maps. The specular map looks funky, but that's nothing special; the dress just looks that way.

The file names are as follows:


I'm not sure what alb stands for, but it's clearly the color map. Spm and Nrm are SpecularMap and Normal, respectively.

Here's another example: the weird sashimi thing on her head.



In addition to the three expected Alb, Spm, and Nrm maps...





...There are also three other maps labeled Tcl, Emm, and Rft.





I'm assuming Emm is for Emission, to control the light given off by the slab of raw fish on Callie's head, but I simply cannot think of what Tcl and Rft could be.

Oh yeah, and don't get me started on inkling color or jellyfish transparency.
