The horned melon (also known as "blowfish fruit" in the U.S.) is a member of the cucumber and melon family that is native to Africa, but now grown in a variety of places worldwide. Known also as the African horned cucumber, jelly fruit, and English tomato, eating this fruit is like biting into a cucumber that tastes like a banana.
With an inedible and hard exterior that resembles an acorn, the Mangosteen contains a soft, tangy and sweet interior. There exists a legend about the fruit, dating back to Queen Victoria, where she offered a reward of 100 sterling pounds to anyone who could deliver the fruit, the likely source of it's unusual designation as the "Queen of Fruits."

The Romanesco broccoli (or Roman cauliflower) looks a lot like an alien egg, but is actually an edible flower and variant of traditional cauliflower. Prepared like regular broccoli, it is most suited for raw crudites and has a more creamy and nutty taste.
With a spiky exterior that makes it less than ideal for playing sports with, the durian holds a fruit in its interior that is known for strong reactions (both good and bad) from the odor it emits. The odor is so strong that it often penetrates its husk even when intact, resulting in its banishment in Southeast Asia from certain hotels and some public transportation.
The chayote looks a bit like a pear on a real bad day, but is actually a fruit that is native to Mesoamerica, a member of the gourd family. It is contended to be a rather bland fruit, like a mix between a pear and a potato, so is often marinated with lemon or lime juice when prepared.

Looking a tad bit like larvae, the crosne is actually a root vegetable that has a nutty, artichoke-like flavor, with a white and tender flesh.
They may look a bit like green apples that were beaten up a bit, but the cherimoya is a fruit that Mark Twain once dubbed "the most delicious fruit known to men."

The Lychee has a hard shell surrounding a very soft and sweet fruit that is perfect for snacking on or making a martini with. Exceptionally sweet, eating a Lychee feels very similar what you would imagine eating an eyeball would feel like (not that I have).

Looking like a cross between a tomato, peach and apple, persimmons are an edible fruit that are usually eaten with the skin peeled off. Like the tomato, the persimmon is not considered a "common berry" though both are "true berries."

Unlike other citrus fruits, its raw rind is sweet, with the flesh acidic and sour like the lemon.
