Players should be able to switch through entity poses. For example, a player morphed as a Dog should be able to lie down and sit.

EPIC idea! 👍 🥇

I dont think this has been done before with a morph mod yet so this would be the first! and most epic awesome idea! 👍

Example for Armor Stand identities:

1. No arms
2. Show arms
3. Show arms and use humanoid animations

(the ability key could be used to toggle showing the base plate, with no need to sneak)
