Fortnite: How to get infected by an Alien Parasite and talk to Sunny explained
Despite everything, it's still you.
Appearing during Week 5, it follows the tasks of getting orders from a payphone, interacting with a CB Radio, deploying alien nanites and doing a dance near Zig and Choppy.
Considering Sunny's location isn't exactly one surrounded by Alien Parasites, this presents an interesting obstacle to overcome.
After roaming around the battle royale map for a while, we've found a spot nearby that should make this challenge a breeze. Doing so will reward you with 30k XP, which will help you unlock Battle Stars for the Season 7 Battle Pass.

How to get infected by an Alien Parasite and talk to Sunny fast
As you might have noticed in the previous challenge, Hydro 16 is filled with Alien Parasites, which would make for a guaranteed go-to in order to complete this task. The problem is that it's quite far from Sunny's location.
In case you haven't greeted her yet, Sunny can be found all the way up on Believe Beach's coast. It's a long way from Hydro 16, so we're going to avoid doing that. Instead, you will be landing east of Pleasant Park near the spots marked on the map below:

Based on our experience, this was the closest location we could find that always had Alien Parasites around. The exact spawns may vary, of course, but it won't take you long to see the green hatching eggs.
When in doubt, you can look for infected chickens, as in most cases that's a signal of a nearby parasite.

After you've found a green egg, get close enough (on foot) for the parasite to break it open and attach itself to your head. Now, we highly recommend for you to secure a car to get to Believer Beach. We have seen vehicles near the bridge, as well as in Pleasant Park's gas station.
From there, all you have to do is drive to Believer Beach, which shouldn't take you long. By nature, Alien Parasites will detach themselves momentarily from your character if you happen to get in touch with water, but this does not apply if you're in a car, so just head towards Sunny at full speed.
The alien invasion of Fortnite continues with the arrival of mothership abducting, UFOs, Alien Artefacts, Cosmic Chests and ray guns. There are new Epic Challenges each week to be completed, including finding Nuts and Bolts, fishing spots and porta-potties. Elsewhere, there are time-limited Legendary Quests starting every Wednesday, with the latest steps including finding Sunny, Joey and Beach Brutus locations, Welcome signs, Boomboxes, Alien light communication devices on mountain tops and Cat Food locations.
Sunny is on the right side of the pier. In order to complete the challenge, you must have the parasite still attached to you, and then talk to her. After the dialogue, the task will be over. Keep in mind that players have been killing Sunny in several matches we were in, so try and follow these steps as soon as possible!
