Except for the fact that it's fun..?
You can get coins and prizes from your friends! As well as look at how other people doing🕵🏻
Tap the Phone button, pick a friend, and come to their home location.
When on the location, you can see the purple energy points. Tap on different objects, use energy, and get Frendium and Coins in exchange.
Later on, you can use Friendium to leave gifts for your friends. Tap on the Gift button in the right-bottom corner of the screen and choose the gift. After you spend your friendly energy on open friend's location, come to other friends. After some time friendly energy will replenish.
P.S. Don't forget to take your Pet with you to get a chance to get water💧
Have a great time😊
