This challenge is part of the Meowscles Mischief Challenges, the third agent Fortnite Chapter 2 Season 2 focuses on. You'll have to dance in the middle of three distinct locations: Lake Canoe, Camp Cod, and Rainbow Rentals. You don't even have to complete your performance in one single game, so all you have to do is know the locations in each area to complete the challenge in less than two.
Meowscles loves fish, and he lets us know it through this challenge. Camp Cod is located at the extreme south of the map, on the great peninsula. It's a kind of dump with a rather modest loot but where you can easily harvest metals.
These small seaside cabins are located southwest of Holly Hedges. They're recognizable by their striking colors. It's a decent spawn, but relatively far from any other point of interest.
If you're diligent in your challenges, you should be familiar with this notable place, located west of the Grotto. This isn't the first time we have had to go there! You can recognize it from afar with its boats placed one on top of the other, on the small central island.
Remember that Team Rumble can be an excellente option as you'll encounter fewer belligerent enemies in the area. Keep in mind that you'll need to activate a dance emote once you've arrived at each location. Make sure you have one in your emote carousel!
