This is an absolute absolute internet hoax. Those who have mentioned this to be sacred, spiritual, tribal ritual etc. etc....are you part of the tribe or do you have first hand info and evidence to prove what you are saying? Why is it the same set of pics everywhere? I am very sure you have seen a mango, an apple, grapes, banana - with your own eyes, and on TV, in newspapers. Yuo have even seen the weirdest of things like babies with 2 heads and multiple arms & limbs, the different planets in the galaxy, the volcanoes, plants with canibalistic charecters. How come you have never ever come across this nareeblah before today - moreso in the age of Discovery Channel and Nat Geo?
It is good to be a believer, but make sure you have some evidences to substantiate what you believe in. Beleiving and being gullible are two different things. Don't be gullible. You are smart enough to know better. This whole thing is nothing but a very well performed hoax by an extremely talented individual who has taken the pains of making up such a story, making up very good pics and then publishing it on wherelese - the net. Think about it!
