The method of obtaining the velvet jewelry box in the Fat Goose Gym is that when friends reach a certain value, it is possible to unlock the prop "velvet jewelry box". If the main interface is not displayed, it means that it has not been unlocked successfully, and you need to continue to upgrade or do tasks to open the box.
Fat Goose Gym is a lovely casual game. Players play the role of the manager of the gym, get materials through synthetic gameplay, create a unique gym, and attract cute fat geese to exercise.
