Let's Re-think Mangle's Endoskeleton - Model Showcase (Five Nights at Freddy's)

Here we analyze, break down, and re-make the endoskeleton for Mangle from Five Nights at Freddy's, trying to tidy up the model without going so far as to stray from the core design.
This is the model I made for my Five Nights fan-animation 'A Distant Voice': • A Distant Voice (Five ...
A few extra tidbits about the model that aren't covered in the video:
The addition of the tail and the parrot on Foxy's shoulder are not especially canon, particularly not the parrot. I included them as useful places to justify having extra limbs attached, and I had the freedom to take these kinds of liberties since we never quite see pristine Mangle in the game. We have a solid idea of what the design looks like, but it's always at least one step removed from canon, such as the stylized version in FNaF World or as part of the series's line of merchandise.
One odd little clash between Mangle's before and after states is the pirate hook: In depictions of Toy Foxy, the traditional hook is there, including in a pre-release teaser from before FNaF2 released. But the actual model for mangle has two hands instead. Also strange is that Mangle's model has the spherical bunny tail from Toy Bonnie instead of the fox tail seen here. I made these changes to my version to fix what I can only assume is just some minor continuity errors and/or shortcuts taken when making the original model. FNaF2 was made in an incredible rush to strike while the iron was hot after all, so oddities like that are to be expected.
