I just bought a Gemmy singing edwardian butler prop from a guy online but I can't seem to get him to stand up? I believe everything else works on him. He sings, mouth moves, head and body turns, eyes glow, microphone works, etc... I believe I am supposed to step on the button on back and just pull up (but not sure). When I try that , nothing happens. I just noticed that theirs 2 plastic screw type on the very bottom, I tried to remove them thinking perhaps this help locks him down in place... Any suggestions or idea as to what to do????
