There's a fishing village on Penang's border.  Here you find a long-kept & unique tradition. The fishing village is called Kuala Muda. They run a fish market, &  hold an auction to sell their catch. But what’s really unique is that for some wildly bizarre reason they hold a whispering auction.

Sapeken is a tiny oval shaped island in the eastern Kangean Archipelago, north of Bali, east of Madura, in Indonesia.

The people of Kangean’s main island seem to be dominated by the Madurese, but with of Bugis (of “Boogey man” fame), Makasarese & Banjarese—all the seafaring peoples of east central Indonesia—mixed in, both in their family trees & in their language.
