Step 2
This is a shot of the Lego motor that extends the tongue in and out. It is based upon a rack and pinion to move it back and forth using a Lego geared motor from a Mindstorms set. It is controlled with a 6v lego handheld motor from a technics set.
This was the most difficult part of the costume, finding a mechanism to extend the tongue. I tried and rejected many alternate mechanisms. It is mounted inside the mouth. Take care to mount it such that someone that reaches forward to push on it can't accidentally push it into the face of the wearer.
I was so enthusiastic that it worked that I didn't take as many 'in-process' shots as I should have!
