In order to pass through the Islands of Special Event, it is necessary to have Provision - Bananas.
Initially, there are 60 units of Provision available.
Provision can be refilled by going into the Island and finding Boxes with bananas.
There is no need for searching for boxes manually. Instead, a Tree can be used - Banana palm.
When an exclamation mark icon appears above Palm tree, it means that a box with Provision has appeared on the island!
Just click on the Palm tree and the game will show you where to find it.
Do not worry if the box shown by the Tree is inaccessible.
Provision appears every 10 minutes in different places. [In total, up to 6 boxes at a time can be found on the Island.]
In the meantime, missing Provision can be purchased for Gems. Click the Provision icon in the upper right corner of the screen.
A new window will appear, showing the number of bananas available for purchase.
Pay attention: the amount of Provision purchased will not extend the maximum in total.
E.g., on the picture below you can see that only 11 bananas will be exchanged.
