It's Week 9 of Fortnite: Chapter 2 Season 4 and for this challenge, you'll need to find and dance at the highest and lowest points on the map.
You'll be travelling from one end of the map to the other to complete this weekly challenge, so try to land at either location straight from the Battle Bus and grab a weapon when you can.
The good news is that you don't need to complete this challenge in a single match, so don't worry if you can't cross the map in time. While you've likely visited the highest point on the map already in previous challenges, the lowest point is one of the newer locations.
The Fortnitemares challenges are now live, so you can always float your way over as a Shadow if you're eliminated early.
Fortnite: Chapter 2 Season 4 - Dance at the highest and lowest spots on the map
The highest point on the map should be quite familiar to you. Mount Kay can be found at the coordinates G7/G8, so head there first and use your favourite dancing emote once you reach the flagpole at its peak.
The lowest point on the map can be found at Coral Castle, in a little temple with a pool near the centre of the location. Wade as far into the water as you can while still being able to use your dancing emote to complete the challenge.
You'll need to keep the emote running for a few moments for each location to register as complete.
And that's it! You can find our guide for the Wolverine skin challenges here, as well as how to eliminate Stark Robots at Quinjet Patrol landing sites and all the map changes so far.
Here's where you can find the Black Panther memorial at Panther's Prowl and where to ride a motorboat under different coloured steel bridges.
