The Dink Network

In the d-mod I'm making, I'm trying to get rid of Dink's fists, but am a little confused at how to do it. Below is my attempt at making it work (with a few other commands). I know I'm doing something wrong, but what?

void kill_this_item(item-fst)
{
}

VOID MAIN(VOID)
{
freeze(1);
sp_nodraw(1, 0);
sp_speed(1, 1);
push_active(0);
sp_brain(1, 1);
sp_base_walk(1, 330);
sp_base_idle(1, 330);
}
