Before you complete any song, from the main menu, go to My Zumba, the select Challenges, and pick a challenge to 5 star all songs in one of the locations (Hawaii, Los Angeles, Puerto Rico, Brazil, Caribbean, and Europe). Then play the 5 songs from that location and 5 star them. This will unlock the stickers and badge for that location. Repeat for the other 5 locations. The achievement will unlock upon completing the last song.
