Pokémon Model Ripping Project

[Random Talking Bush]

I know this may not be the right place to post this, but I really don't have the choice as there isn't a Gmod section here.
I have already posted this on Facepunch, but they didn't really help me out that much.
Anyways enough of rambling. Lets me just get this straight.
For the past few days, I have been trying to figure out why the model is acting like this.

So far, I have failed to find the solution to this problem and I need some help in figuring out on how to fix this stretching problem.
The files are here in case if anyone wants to help me tackle this problem.
If anyone wants to help me out in this issue, just send me a PM.

Make "Waist" the root bone in the QC, not "Hips". That's why it's stretching like that -- you essentially made the model have two separate roots by doing so. Also you have waaaaaaay too many physics joints in the model, you can only have a maximum of 32 and you've got 55. You'll need to remove the fingers, nose and all of the "feelers" from the limitations to bring it down to 28, but you'll need to make a physics model to go with that (NEVER use the original model as a physics model, you'll encounter dozens of problems by doing so, you'll want to build something akin to this with segmented joints instead for the physics).

I've made tons of things for Garry's Mod before, so I've dealt with these kinds of problems.
