2. In one design try instead of him hitting the water pipe, have him backed away a little and have his lips puckered looking like he is about to cough (as if he just had taken a hit)
3. Try another one where he is holding the water pipe in one hand, and holding a torch in the other hand heating up the nail (as in the picture provided above) this is what the torch looks like, http://www.butanetorchshop.com/wp-content/uploads/2012/03/jewlers1.jpg if you could have the torch look like yoshi, or another customized looking torch....
