I personally re-animated the Teddy Bear’s idle twitch because the BO3/BO4 version was too goofy.

In case you don’t know, there is a rare chance for the teddy to move ontop a box location.
This started in BO2, and was far creepier and only moved its head (which I replicated).
In BO3/BO4, it instead floats and pivots its body, which is far too silly.
