Worm

The Worm is a Mob that can spawn when mining tunnels inside the Crystal Hollows.

Spawning
A Worm or Scatha has a  chance of spawning when breaking Hard Stone in a tunnel of any width and height within the Crystal Hollows. A Worm has an chance of being spawned while a Scatha has a  chance of being spawned instead. The Heart of the Mountain Mole perk will not prevent Worms from spawning.

After digging out a suitable tunnel, breaking the blocks at the player's eye level on the side can still trigger Worm spawns. Breaking the blocks at foot level will not trigger spawns but breaking below foot level will.

While spawning, they make a unique squelching sound 3 times, alerting players of their presence, and the message "" will appear in chat.

Behavior
A Worm appears as a chain of heads with the same texture of the Scatha Pet, and will slowly slither through the tunnel it spawned in. It has and deals. They start off with a chain of 5 segments, which decrease by one each time they are hit until killed. Each hit dealt to a Worm will deal of damage to the Worm.
