do you mean the stand leg?
you really need the leg to enjoy playing. i cant imagine how the vb holds in the right position without one. maybe you can build a leg, but i would prefer a complete vb.
well, there are some positions you can play without a stand leg, but that could make headache. its much more comfortable to paly with a stand leg, so get a complete one.
I could buy some equipment on the official Nintendo web page. But they don’t have much stuff left. Go take a look maybe you could find something you want.
