What does each fruit do?


Hi I am unsure what all the fruits do.
I understand the apples and tomatoes give you more crystals when tapping for a designated amount of time but I don’t quite understand the others. Could you please provide a list of the fruit and their functions?
For example I have used the banana twice now and still have no idea what it does, what do the pluses either side of it mean?
Thank you


Special fruits like apples and tomatoes continuously produce crystals when you tap the screen. Other fruits give you extra crystals (in one go) when Wokamon consumes them.
