You live in brawl topia a small pirate city, you were at your home alone playing brawl stars, you choosed that you wanted to Play with darryl, you picked him and in this moment someone knocked on The door, you went to the Doors, Instead of looking through the peephole, you look through the keyhole bc why not :) and you see a brawler that you just picked to Play with, you opened the door for him and...

Ahoy mate! Glad you wanted to Play with me!
