A frog, an elephant and a pig challenged each other to race to the shores of Johor. The animals that failed would turn to a stone. They all failed. The frog became Pulau Sekudu (Frog Island); the pig and the elephant became Pulau Ubin – Granite Island.
In Pulau Ubin there are mangroves which are essential to cleaning of the oceans. They can absorb even heavy metals from the sea. How is that for awesomeness!
