In the 1980s, breakfast cereal manufacturer, Weetabix created a British TV advertising campaign for their cereal, turning the Weetabix biscuits into characters called Dunk, Bixie, Crunch, Brains and Brian. This led to a computer game starring Dunk and his mission is to destroy all the Titchies who have set out to destroy the biscuits themselves. Based on Space Invaders, the game is a single screen shooter viewed from the side with Dunk on the bottom of the screen and the Titchies at the top in formation. The Titchies mainly stay in formation but will occasionally move about the screen elsewhere.
