Ghost (Wario Land II enemy)

Ghastlys are ghost monsters in Wario Land II that impede Wario's progress as he recovers his stolen treasure. They are completely invincible in the game. It is unknown if they are vulnerable to light, like Zombie Wario. If Wario touches one of the ghostly enemies, he will become Zombie Wario. These small ghosts always float on a set path, so Wario must move systematically to avoid zombification.
