Zookeepers are non-player characters who work at the Ardougne Zoo. They keep watch over the animals and clean up after them. Players can talk to a zoo keeper named Larry to start the Cold War quest and can also talk to a zoo keeper named Charlie to start the Eagles' Peak quest.
Players doing Treasure Trails clues are sometimes directed to him with the anagram 'Eek Zero Op' and are given a challenge scroll.
The answer is 40 +1 if Eagles' Peak is completed, +1 if Hunt for Red Raktuber is completed.
