Let's ask the Tomato and the Cucumber if they are fruit shall we? Sam: Are you guys fruit or veg? T&C: *Nothing but silence*
Of course jalapeños are fruit as well as cucumbers and tomatoes. Fruits are basically classified as a plant that contains it's seeds, the only exception is the one fruit which actually has its seeds on the outside of the fruit which is a strawberry. The reason there is confusion about what is a fruit and a vegetables is that many fruit are actually considered vegetables for cooking purposes, I think mostly because they lack the sweetness fruits often have. On a side note, I'm still loving the update and I unlocked everything. Can't wait for the new mode to be released.
I think you could add "Peaches of Immortality" from Chinese mythology. They could be a rare fruit and when you slice one you earn back a life. ...you could do the same with Golden Apples...also granting immortality in Norse mythology.
