The Skulk Corpse Worm

I noticed that deep caves, especially in the Bedrock Edition, often feel overcrowded with standard zombies and skeletons, which ruins the atmosphere. I want to propose a new, invincible horror-themed mob that challenges the player to be more careful, rather than just fighting waves of monsters. Name: The Skulk Corpse Worm Appearance: A large, segmentary, centipede-like or silverfish-like worm covered in dark-blue skulk scales with glowing cyan eyes. It can crawl on walls and ceilings. Mechanic: • While the player is at full health, the worm remains completely neutral. It stays in the shadows, climbing on the ceiling, and just watches the player. • The moment the player takes damage and drops to low health, the worm detects the "weakness/heartbeat" vibration. It turns aggressive and attacks immediately. • The Counter-play: The player can place and ring a Village Bell. The loud metal resonance temporarily "blinds" the worm's skulk senses, instantly resetting its aggression back to neutral. This would add an incredible psychological horror element to the Deep Dark and give a unique survival utility to the village bell!
