I'm on version 7.2.2 but I cant get to Annies's part of the game. below the animations thing the Annies expedition button isn't there
You gotta finish hailey's game, then talk to the zombie girl in lvl 14 for hint on finding the girls in different levels. You'll unlock Annie's content that way
Or just go to Lags' Youtube account and watch the vid about all the easter eggs (Hidden treasures, hidden girls to safe, hidden idk..)
