Scatha

The  is a mob that has a chance to spawn when mining Hard Stone.

Spawning
The Scatha has a chance to spawn when the player breaks blocks within a tunnel 1 block wide, 2 blocks high and 5+ blocks long. When the appropriate conditions are met, the Scatha will have a chance to spawn upon breaking the next block. They spawn about 3-6 times less often than Worms.

After digging out a 1 wide 2 high tunnel, breaking the blocks at the player's eye level on the side can still trigger Scatha spawns. Breaking the blocks at foot level will not trigger spawns.

While spawning, they make a unique squelching sound 3 times, alerting players of their presence.

Usage
They appear as a chain of heads with the same texture of the Scatha Pet. Every hit will remove 1 from their health, similarly to Spooky Festival mobs. They start off with a chain of 10 segments, and decrease by one each hit until killed.

Upon spawning, they will slither away from the player.

Trivia

 * When using the Mole perk, the player will not be able to spawn Scathas because the tunnel dug will not be 1x2. However, if the player mines in the west direction, they will be able to spawn Scathas.
