You mean the Changing Ponytail? Yeah, I've got that, and the Expansion and the "Maps and Poses" expansion... the only one that should come with any pose files is the maps and poses pack, and that doesn't include any MATs, just MORs... Unless you've got the Vicki A2Z set, you'll have to apply it's textures by hand (Why the A2Z pack came with MATs for the Changing ponytail, I'll never know, but I'm not complaining...)
