Couple of things:
•drill small hole in head and remaining neck piece, insert small revoltech joint. Works, adds range of motion, but wario has to look down to hide the joint unless you want to dremel out a chunk on both halves to hide it.
•dremel out a chunk on both sides and superglue an nd magnet in both halves. Works, but head can be removed, which is more pro than con to me.
