Trolls are very weak enemies that appear early in the game and once again near the end of the game. They are among the few enemies that the player can't play as besides the large bosses. Trolls are known to ambush in high quantity, creating the only real danger from this enemy.
The Trolls usually hide and spring out when the player passes. They appear as diminutive, black, fur covered balls of sticks.
