Issue

Creaking mobs can be pushed by any other entity when not being observed by the player. It was specifically stated that creaking are meant to be "rooted" to the ground and immovable outside their own volition. However, other mobs, and even the player themselves, can move them if they walk into the creaking's hitbox if the player isn't looking at the creaking. I'm unsure whether this is intentional behavior.

Steps to Reproduce

1. Locate or spawn a Creaking.
2. Switch to third-person perspective (viewing them in this way does not count as observing them, so they can still move on their own).
3. Position yourself in front of a Creaking and then turn away from it, so that it is directly behind you.
4. Walk backward into the Creaking.

Observed Result

The Creaking is moved easily.

Expected Result

The Creaking would remain immovable by others.
