Sunnyboy, were a popular Australian brand of flavoured ice block, well known for its distinctive tetrahedral shape (a design called a tetra-pak), sold individually or in packs. The ice blocks were extremely popular all the way through to the early 1990s, being cheaply available throughout tuckshops, discount stores and milk bars across Australia.
The four flavours each had different names: orange flavour is a 'Sunnyboy', raspberry flavour is a 'Razz', lime flavour is a 'Zap', and cola flavour is a 'Glug'. For a brief period in the 1970s, a pineapple flavour, called 'Pow" (later 'Big Daddy'), was available. Another was 'Hawaiian Punch'.
In 1991, the recipe and Sunnyboy brand were bought by National Foods. Since this time, availability of Sunnyboy ice blocks decreased yet they still remain popular and come in three flavours; orange, raspberry and cola. In 2006, a Sunnyboy cordial brand was released which included eight flavours; lemon, apple berry, mango mandarin, pinelime, strawberry watermelon, fruit cup, raspberry and orange.
In late September 2016, manufacturer The Daily Juice Co. announced they were no longer manufacturing the product due to a reduction in consumer demand over several years.
