Well, these little fellows have provided a little bit of a challenge to me. They have "semi-standard" legs (it is all one piece) but these guys don't bend. So without wanting to damage the "unknown" inner workings, I went to pure ingenuity: Wide Rubber Band (wrapped multiple times around the neck and head after removing the hair) and I have these awesome pliers that are sort of needle-nose that allow me more leverage.
A simple pull and apart he came.
Now I only need about a dozen more of these for some customs...
