This season 7 week 3 legendary quest requires you to place 3 boomboxes at Believer Beach.

The cosmic summer part is in full swing at Believer Beach. Although based on this quest it seems like they need moroe music to make it better.

There are 3 locations where you can place a boombox.

The first is on the east side of the beach where Sunny is located.

The second is in the middle parking lot that looks like a disco has been set up.

The third is by the caravan park. It's beside the road on the other side of the white fence.

See the map and watch the video below for the precise locations.
