The King & Queen Chompers are two unnamed characters seen in two adverts for Cadbury's Chomp in Australia in the late 80s and early 90s.
Information about them is inexistent, it's not even known if they were successful enough to get more than two ads starring them. The first ad aired in 1987 and used puppetry to animate the King, Queen, and servants. The king reflected Caramel flavour Chomp and wore Caramel-coloured clothing to illustrate that flavour. The Queen reflected strawberry flavour and appeared with a strawberry for a head and wore pink clothing to illustrate that flavour. At some point there was a new Peppermint flavour released and another king joined the cast. He had green skin and green clothes to illustrate the Peppermint flavour. The peppermint flavour ad was created in CGI instead of using puppetry and was released in 1990, although one YouTube upload says "around 1987".
