We bought the coconut that my mom is holding and we watched our salesman use a machete to cut of the top of it so we could drink the water!
Here is everything we bought.. yum! Yes you can eat those red spiky things in the back. You cut them open and inside is a kind of fruit that tastes like a grape but it has a seed in the center.
Here is my mom, getting all of the "meat" out of the coconut!
