Tesla car owners will soon have the option to choose sounds like farting or goat noise for their vehicles' pedestrian noisemakers and horns, Elon Musk has hinted.

Musk also tweeted about adding coconut sound as part of Tesla's customisation exercise.

"Customised horn & movement sounds (coconuts being one, of course) coming to Teslas soon," Musk tweeted.

Musk also teased goat bleats, rushing wind and coconut horse clops from the comedy movie "Monty Python and the Holy Grail".

In another tweet, Musk also mentioned adding a whoopie cushion noise (made famous by Tesla's "Toilet Humor" mode) and a goat noise, reports Teslarati.

Goats destroy Greek Island

A Greek island, Samothrak, has goats outnumbering human inhabitants 15-fold and they are munching stretches of Samothraki into a moonscape. After decades of trying to find a solution, experts and locals are working together to find a 21st-century way to save the island's ecology and economy.

Semi-wild, the goats roam across the island, which is roughly three times the size of Manhattan, and can be spotted on rooftops, in trees or on top of cars as they scour the landscape for anything to eat. Their unchecked overgrazing is causing crisis-level erosion.

Torrential rain two years ago swept away the island's town hall and severed its roads. There were no trees or vegetation left on the steep, goat-eaten hillsides to stop the mudslides caused by the downpour.

"There are no big trees to hold the soil. And it's a big problem, both financial and real because (the mud) will come down on our heads," says George Maskalidis, who helps run Sustainable Samothraki Association, an environmental group.

The goat population, meanwhile, soared fivefold to an estimated 75,000 by the late 1990s. Some parts of the countryside were simply nibbled away.

The goat numbers have since dropped to below 50,000 as there is little left to graze on. But this has left the island in a trap.
