This is just so obsurd to still be dealing with it. Obviously, the Yeti will never operate in it's glory as the whole structure is in jeopardy due to foundational stresses. I'm sure there is an affordable (under $1m, perhaps a few hundred $k) to replace the mechanism so his arm still has some movement then reprogram him so his face is fully operational (minimal stress) along with the lightened arm. He was really cool when he moved completely as you'd swear "it" was going to jump onto the track and eat you. However, as quickly as you see him, having him let out a piercing growl, follow the train with his head movement (while looking & growling) and taking a much lessened swing with NO full body movements is doable. Even if it meant removing him during a few nights, do concrete repair/replacement to be able to support an almost motionless Yeti, then re-install with the lightened arm mechanics and new software. It would still look amazing (using the same skin and shape), operate much smoother and damage free, and provide real thrill value. I for one doubt many people would know the difference between this suggested mod and the original.
