Force NPC Animations Onto Player?

Hiya! So after playing various Clockwork schemas, I got curious as to why everyone has the animations of their current model’s NPC counterpart.

So my questions are:

Why is this so,
and is there a simple way (hah probably not) to replicate it an addon format? (rather than tampering with a gamemode).

Thanks!

Just tamper with the gamemode and recreate as an addon.
