Silverfish are small grey Mobs that only spawn in Strongholds. They move in a wiggling pattern and make a hissing sound similar to that of a Spider's. Silverfish can spawn in the blocks of Strongholds when you destroy certain blocks, and at The End Portal where there is a Mob Spawner. They have low health but spawn in numbers.
- They make a sound like a salt shaker does when they are moving.
- When one gets hurt, more will spawn around it.
