Ever wanted to use a festivizer on yourself? Yeah me neither, but now you can!
Some festive lights to to put on your body, definitely where they're meant to go. Includes blendshapes for breathing, female and muscles.

Setup:
Add the prefab to the scene, parent "Christmas Lights" alongside the Rex's armature and assign the parent constraints on each light bone to their corresponding Rex bone.

Notice:
The shader used is Poyomi's Toon Shader (which is not provided but is free online) though other shaders can work.
