This challenge is part of Fortnite Season 4 Week 9 Challenges and you'll have to dance at two distinct points on the map: the highest and lowest geographical point. These are of course not mentioned by name on your mini map, and can be difficult to identify.
Don't panic, below are the exact locations where you'll have to perform your choreography.
Map
The highest point of the island is the summit of Mount Kay. This snowy mountain is located at the south-east of the map. The summit is marked by a red flag. The lowest point is the center of Coral Castle. Logical, since this location arrived during the previous season is actually below the ocean level.
Keep in mind that these two locations will be quite coveted during the week following the release of the challenge. Many players may land directly on the spot and could kill you before you can perform your dance.
There is nothing to stop you from venturing there a little later in the game. If you really don't like to take risks, the Team Rumble mode will allow you to complete the challenge too. You'll have less chance of encountering aggressive enemies, and if you run into trouble, you can reappear endlessly.
