Generations of Sunnyboy lovers were left shattered on Monday when it was announced that the flavoured ice blocks were to be stop being made.

The Daily Drinks Co released a statement saying there had been a 'sustained reduction' in the demand for Sunnyboys, and they will no longer be sold, Kidspot reports.

'No other products are affected by this deletion, and consumers will still be able to purchase all our other popular brands, including Zooper Dooper and Quelch,' the company said.

Sunnyboy flavoured ice blocks to stop being sold in shops despite being a childhood classic

But for many people around Australia the popular brand of distinctive tetrahedral shaped ice block will be sadly missed.

The cheap ice blocks, which were sold in tuckshops, stores and milk bars across Australia, were hugely popular from the 1960s all the way through to the mid-1990s.

A pang of nostalgia will also hit lovers of the icy treat just by hearing the names they were called.

The original orange flavoured one was known as a 'Sunnyboy' or 'Orange Explosion'. Raspberry flavour was a 'Razz', a lime flavour block was a 'Zap', and a 'Glug' was the name of the cola flavoured variety.

Some of the popular treats were called the 'Orange Explosion', 'Razz', 'Zap' and 'Glug'

In the 1970s for a short period there was a pineapple flavour, called 'Pow' (later called 'Big Daddy'), while another type was the 'Hawaiian Punch'.

However after the Sunnyboy brand was bought by National Foods their presence in shops greatly decreased.

Despite a Sunnyboy cordial brand being released in 2006, which included eight flavours, nostalgia was unfortunately not enough to keep the brand on the market.
