Corpse Controllers!
Later on, people also called them Corpse Herders.
*****
It was not good to run into such people.
Corpse Controllers could use all sorts of methods to control zombies and make them attack their enemies from a distance. Corpse Controllers themselves would either stand at a spot very far away from the battlefield to control the entire situation or ambush their enemies from the side. They always brought a great threat to their enemies.
When controlled by the players, zombies became even more agile and difficult to handle. Hence, Happy had only noticed the zombies when they ambushed him.
Fortunately, he was well-versed in adapting to emergencies and sudden enemy attacks, which was why he was not shocked by such a simple ambush. If another player had seen two terrifying zombies pounce on them from the dark, they might have been utterly terrified and unable to keep their composure.
