Converse with Sunny, Abstrakt, Dreamflower, Riot, or Bushranger is a challenge in Fortnite Season 7, and it is one of the weeks easier tasks (provided you know where to look and can manage to avoid other players).
There are a variety of different ways you could go about completing this challenge, but the most efficient way to go about it would be to speak to Bushranger, Sunny, and then Dreamflower, in that order.
If you are lucky and keep a low profile, this can quite easily be done in a single Fortnite match, as each is located in fairly close proximity to the other.
Converse with Sunny, Abstrakt, Dreamflower, Riot, or Bushranger Locations
To start, drop to an area to the north of the Aftermath, where the Spire used to be in the middle of the map.
Landing in the northern part of the purple terrain will allow you to get your bearings, and follow the river northwards until you find him.
Sunny Location in Season 7
From Bushranger, carefully make your way northwest along the river until you arrive at the coast near Believer Beach, making sure to avoid firefights (if possible!).
You will find Sunny standing on the pier, which is located by a restaurant. She is pretty easy to spot, as she is right out in the open
From Sunny's location, head southeast in the direction of Flopper Pond. This journey is perhaps where you will be most vulnerable, so keep an eye out for ambushes.
You will find Dreamflower inside the house at Flopper Pond. Simply talk to this NPC and you are all done.
You'll find Abstrakt in the northern area of Retail Row. Look behind one of the building, hovering around some graffiti.
You'll find Rook in the area south west of Dirty Docks. Head into the larger lab building, and he'll be standing in a room waiting.
That wasn't so bad, now was it?
