What are all the fruits in fruit ninja

Watermelon
Mango
Pear
Peach
Red apple
Green apple
Passion fruit
Strawberry
Lemon
Lime
Orange
Bananna

Pomegranate (Sometimes appears in Classic Mode and you had to slice it several times as fast as you can)

Dragonfruit (It is a rare fruit and if you slice it, you'll get bonus)

Starfruit (Now in the game, if you slice it you'll get a certain amount of "Stars", these "Stars" can be used to unlock blades/backgrounds and more)

Also, in the Arcade Mode there's multi colored bannanas that give you certain bonuses.

I believe there will be more fruits featured in Fruit Ninja in the future. I might didn't catch any other fruits in this answer but I tried remember the best I could. (: Hope this helps you.
