Creaking Gimmick/Weakness Ideas

Having seen the Creaking in action in the newest MC Live, I think I have a few ideas of my own for it: 

- They could be deterred by/stay away from fire, magma, and lava since they're made of wood and would naturally want to stay away from fire sources. (Torches wouldn't count since they're technically more of a light source.)

- Creakings spawned by a placed Creaking Heart could be passive towards the Player who placed the heart there to make them more reliable guards a la constructed Iron Golems.

- They could have different variants depending on what type of wood their hearts are placed between to add more variety to them.

Regardless, I look forward to when the Creaking, the Pale Garden, and whatever else is planned to come with them arrive. Thank you for reading and I hope this helps.
