The Drowned Zombies are uniquely skinned zombies that were added during the Days of Summer seasonal event between July 31st, 2018 and August 28th, 2018. They can be encountered in The Darkest Shore and U.S.S. Mount Olympus after the event.
Drowned Zombies appear either as standard zombies or Wüstlings with starfish, seaweed, coral, barnacles and others sea life all over them, as well as hooks and harpoons. When killed during the event, Drowned Zombies drop a fish which gives the player 10 jolts when picked up.
