Adding articulation to DSE Spanish Buzz?

I picked up the Spanish Buzz awhile back. Just like Advanced Talking Buzz, his right arm (laser and karate chop) has hindered articulation- the elbow doesn’t swivel and the arm doesn’t pivot at the joint. theclearancebin.weebly.com/revie … -buzz.html - not my review, but the link is there to illustrate what I’m talking about.

Is there any way I can rectify this, while keeping the electronic and spring operated features working?

Is there a way to seperate his fingers so they all move separately? -Omar
