Usually tourists just relax, swim or walk around, but sometimes they need your help, and some of them may even have some ideas they want to share with you. When they do, a special icon appears over their heads.

Tap the icon and find out what your guest has to offer: coins, flowers, corals, shells or other useful things!
Pay attention to dialogue windows: some tourists require energy units in exchange for gifts.

The higher your level and the more attractive your Island, the more tourists will decide to visit it!
