Scratcher

Description
The Scratcher is a 5-block tall gray humanoid creature that is around Level 8, he is the biggest entity in the game so far, and also very dangerous, his speed is greater than all the others, except The Thing counting on the speed underwater.

Tip:
Get into tight, closed spaces at Level 8, so if he's following you, he won't be able to get in because of his height.

Levels
For now, the only level he inhabits is Level 8, but in the future he might inhabit other levels.
