What plant has spiky green fruit?

There are a few plants that have spiky green fruit, but the most common one that comes to mind is the kiwano melon (also known as horned melon or African horned cucumber). Its fruit is oblong, bumpy, and covered in spiky protuberances, making it a distinctive and eye-catching fruit.

Here are a few other possibilities:

* Hedgehog cactus (Echinocactus grusonii): This cactus has a round, spiky body, and while not technically a fruit, its flowers can produce small, spiky seedpods.

* Certain types of prickly pears: Some varieties of prickly pear cactus have spiky, pear-shaped fruits. However, most prickly pears have smooth fruit.
