Two of Australia's favourite lollies are about to become a thing of the past, as confectionery company Allen's has ceased production of Spearmint Leaves and Green Frogs.

A spokeswoman for the parent company for Allen's, Nestle, said the only reason production had stopped was because the sweets were not selling.

"The situation is that our lollies are actually going gangbusters, but we have deleted a couple - we have deleted Spearmint Leaves and also the Green Frogs basically because they weren't selling so well," Margaret Stuart said.

"The Red Frogs are going gangbusters though.

"They outsell the green by 10 to one."

But Ms Stuart denied reports that Sherbies and Oddfellows would be going the same way.

"A lot of the things in the paper today are not true - we're still keeping Oddfellows and Sherbies, and most of our lollies are exactly the same as they always were," she said.

Ms Stuart said "lollies come and go a bit" as tastes change across generations.

"Over the last 10 years, we've seen a few of the older ones go. Jelly Tots went about 10 years ago, Violet Crumble bags went about five years ago, but that tends to happen," she said.

"We've also introduced some new ones, but you know the old favourites are still going very well."

She said the company's Killer Python had shrunk in the past year, but Red Skins would remain the same size.
