3DS Smash Bros Model Ripping

I have come across a file with a .app extension found in the SSB4 game files on the SD card that I downloaded it to. Does anyone know how to extract/view this? If you have found out, please PM me or post here how to do so. I will try to rip as many models as possible.

Thanks!
