Ian was trying to carry PJ while running away from zombies when some monkeys snatched PJ up into the trees to get him away from the zombies. Ian was still on the ground but the monkeys were throwing rocks at the zombies and taking them out. After that epidemic, the monkeys showed Ian where they got their water. It was at this waterfall, and when Ian got there he took as many gulps as he could. Then, the monkeys lowered PJ down to Ian and Ian splashed water in PJ's face to wake him up. When he wakes up, a voice comes on the walkie talkie that they had found in the pit. The voice tells them that the monkeys respect them and that they should follow them because they know where to go. Where will the monkeys lead them?
