You step into the Pale Garden, an eerie and grey variation of the dark forest where even the music doesn't play. During the day you don't encounter any mobs, but as soon as night falls...

Wandering between thick pale oaks, in one of them you notice a strange block, the heart of a creaking. It glows and a Creaking, creepy and hostile mob appears behind you, resembling a crooked tree trunk with three glowing yellow eyes. It doesn't move or attack you while you're looking at it. Its heart protects it from any damage.
