Creaking Girl <3

It's the new Minecraft mob for the new pale garden biome. They spawn in the pale garden when it gets dark, they'll run up and attack you, but if you stare at it think will stop dead in their tracks. They take no damage of any kind, instead they're linked to a new block called the "creaking heart", and the hearts are found in one of the nearby trees in the pale garden. The creaking heart can be silk touched, meaning, you can spawn the creaking where ever you'd like. The reason you'd want to bring the creaking with you, because supposedly they will be able to protect your base or villagers (IDK how True that is since they weren't specific sorry)

TLDR: They are wooden cultures that behave like reverse endermen, and can only be killed by destroying the heart block that they're linked to.
