On Treasure Isle there are 3 different pop ups about Energy Packs…
The first is the least harmful if you click “Ask” your friends can send you an Energy Pack for free.
The second is also harmless if you click “Yes!” it simply opens up the store and you can choose to buy a Energy Pack for 10 Island Cash.
The last could make you spend your Island Cash by accident if you don’t read it carefully, when you click “Yes!” 10 Island Cash will be deducted from your account right then and you will be given a Energy Pack.

Just watch out if you don’t want to spend your Island Cash.
