Ok, so I guess your wondering what this ‘Music Box Preview’ is, so I’ll tell you! On February 20th, a new NPC (non playing character), called Cammie, is going to be giving us loads of fun challenges to do, with amazing rewards! As you may have guessed, one of the rewards is the Music Mystery Box! No need to waste your gems now :D All you have to do is go to beat street, and click on Cammie, and choose the challenge you want to do!
After you finish whatever challenge your are doing, go back to Cammie, and get your reward ;O
I hope that you enjoy doing challenges!
