Have you gone back to the beach the next day? If you went you would see this at the beach. We Bring Him home and take care of Him with so much love, and then this is what ultimately happens with Him Wake Up People, We must respect our Gods. It is better that we should use small idols instead such big one or the idols made from paper (which dissolves easily).
