Another two part request, this Fortnite Week 11 challenge is more fiddly than it is difficult.
You'll be asked to take on an Alien Parasite, and then dance in one of three specific locations - Pleasant Park, Believer Beach, or Lazy Lake.
Where to find Alien Parasites
First, you need to find an Alien Parasite. These little creatures appeared at the same time as the alien invasion, and grant players buffs such as jumping higher and running faster, in exchange for a portion of their health (40).
In a game where mobility is a key factor, getting 'infected' by one of these parasites can become very useful indeed.
You have two options to find a Parasite - from infected animals, or in the slimy substance found on trees.
The best thing to do is land near a body of water surrounded by greenery, allowing for quick completion of the challenge.
Once your new best friend is firmly attached to your head, all you have to do is head to Believer Beach, Lazy Lake or Pleasant Park.
As soon as you're there, drop a dance emote of your choice and enjoy the XP rewards.
