Howler

Description
The Howler is a 3-block tall humanoid creature that is covered in a black substance, it's made of the pits that form its body. He's pretty slow and will hover around Level 0, but if he sees you, he'll run faster, like a player. He's easy to outwit as in Level 0 there are many walls and closed places he can't get into.

Levels
His debut is at Level 0, and it will possibly be the only level he appears.
