As a part of the Fortnite Cameo vs Chic challenges, there is a challenge that has been a popular one for other skins which is to find a hidden gnome. Finding the gnome can only be done if the challenge is in your list, you will not be able to find the gnome if you do not have the challenge unlocked.
Fortnite Hidden Gnome Location
The location of the hidden gnome can be found West of Steamy Stacks, East of Craggy Cliffs and North of Frenzy Farm. It will be found in between a race track, cabbage patch and farm sign on the map, these are all located right to the West of Steamy Stacks. When you narrow down those locations and look in the center of the three, you will see a small hill on the map. This is a hill that overlooks the orchard at Frenzy Farm. This is where the gnome is located.
