A fan group for a discontinued line of Cadbury chocolate has gathered more than 10,000 supporters - and they're not going to rest until their "all time favourite" flavour is returned to supermarket shelves.
Bring Back Cadbury Marble this week called on followers to "spam" the confectionary maker's Facebook page in a bid to convince the company to revive the product, which featured swirls of milk and white chocolate with a hazelnut praline centre.
And they did just that, posting impassioned please on the Cadbury Dairy Milk Facebook pages to "Please bring back Cadbury Marble!!!"
"I have been asking for years and now, everyone else is too. How many people need to ask before Cadbury finally listen?!" one supporter wrote.
"Please, BRING BACK MARBLE ALREADY!!! Nothing else compares and I don't like any of your other flavours so I just don't and won't buy Cadbury unless you bring back Marble."
Another said they were "praying for a Christmas miracle".
Devotees have praised Cadbury Marble as a "melt-in-your-mouth chocolate" with a "smooth, creamy and luxurious" texture that was "delicious and addictive".
But Cadbury Australia discontinued the product in 2012, and has been tight-lipped on whether it will revive it - despite launching experimental flavours such as Cadbury Vegemite, with 1.2 million limited edition blocks quickly selling out despite the fact the flavour was widely viewed as a publicity stunt.
Marble lovers even took to unusual step of writing to Prime Minister Malcolm Turnbull, requesting that he advocate on their behalf.
Cadbury's parent company Mondelez International said in a statement that Marble had been discontinued to make way for other flavours.
"Unfortunately this sometimes means that nostalgic favourites need to be discontinued to make way for the new," the company said in a statement, adding that it was always reviewing its product lines and would take customer feedback into consideration.
