Pokemon Rumble Rush - Bad UVs, need help/advice

[Nooga]

Ok, thanks for letting me know about it!
I'll see about getting it set up in Blender, I'll comment back here if I run into any problems with it.

BTW, how do I edit textures in Blender's UV Editor? I can't seem to figure out how to edit them.

So you want to select the part you want on the model in edit mode, then go to UV/Image and check down the bottom, there's an option to open an image file. Open the applicable texture and from there you can do standard edit mode stuff with the UVs.
