I was amazed at the size of the fruit - like a large watermelon, but spiky on the outside and filled with gooey fibers that surround the edible part. Fortunately, I did not have to extract the fruit myself from the sticky mess. Extremely delicious. Apparently, they grow on tall trees. One of the people who shared the fruit with me used to climb the trees barefoot as a child to harvest at a farm in Vietnam.
