Yoshi Physgun Model / Beam ??

I had this idea of having a Yoshi (head) physgun with his tounge as the beam! I tried to change texture of the beam itself but I cannot. So therefore I wonder if anyone here (more experienced at this) can make one. I know it could get tough but its only the head and imo I think its a great idea. Please reply.
Thanks in advance! :wink:

That actually sounds pretty cool and awesome plus I love yoshi to
