>Tauros>Sharpedo>Lapras>Mudsdale>>29748492There isn't really much in the way of fanservice, really
>>29748494>>29748604>>29748657This whole list checks out, Sina and Dexio have battle models as well, there's nobody beyond those few that I've seen
>>29748624Just download the .cia, unpack it with any .cia unpacker tool and extract the files I listed in the OP with Ohana3DS, the ones with file extensions that aren't .bg and .bin are usually model files
Game Freak is doing the same thing they did with all the games starting with Gen 4 where all the assets are packaged in a very disorganized mess, so it can be difficult to navigate
