They can be spotted at farms northeast of the Corny Complex, as well as in the region south of Believer Beach.While boars can be hunted down by visiting south of Believer Beach and south of Corny Complex, they are also discovered in other areas too. Wolves usually spawn on the east side of Weeping Woods and northwest of Lazy Lake.If the alien parasite infects an animal, its head will be replaced by the alien. Loopers then need to shoot at the animal's body and not at the head. If they shoot at the head, then the alien parasite might die, which will result in nothing.If killed correctly, players can approach the animal, and the Alien Parasite will sneck onto them. Players will notice their HP going down but, on the other hand, will hold the low gravity jump effect and be invulnerable to headshots.This is just the first part of the quest, and to complete the quest, players and receive the rewards will need to visit Believer Beach and talk to Sunny before removing the Alien Parasite.Alien parasites are taking over Weeping Woods and one decided to hitch a ride; figured I’d help support their cause. #FortniteInvasion @FortniteGame pic.twitter.com/bha7EwXYW3— Chris Zaiser (@ChrisZaiser) July 4, 2021Also read: Fortnite Season 7 Holly Hatchery Guide: What can players do in the new Alien-infested POI?
