He's Mr Squiggle and he's back. Having entertained generations of children and no doubt a few adults with the puppet's uncanny ability to turn a squiggle into a picture, Mr Squiggle has now had an uncanny transformation of his own.

Mr Squiggle and his puppet friends from the long-running ABC children's show have made the big time with their own series of $2 coins being produced by the Royal Australian Mint.

Gus the Snail, Bill the Steam Shovel and Blackboard also make an appearance on the coins, which were released on Wednesday. For those unfamiliar with the popular show from a slower era, the Mr Squiggle television series, which aired from 1959 to 1999, was a show in which children would send in their "squiggles" which Mr Squiggle, a puppet with a pencil for a nose, would then turn into recognisable drawings. With 41 seasons, the show became one of the longest-running children's programs on Australian television.

The coins commemorate 60 years since the advent of the character.
