Publisher's blurb Agility is the key to successfully guiding Herbie (the halibut) through the maze, avoiding the deadly gaze of sonic crabs while feeding on delectable night crawlers. The more you eat, the higher your score. Each time you clear the maze of tasty morsels, you will receive more time, additional lives, and a new group of night crawlers, as the game of survival continues. But beware! With the passing of time your presence becomes increasingly aggravating to the killer crabs who lurk within, improving the accuracy of their menacing sonic waves. Set at beginner or advanced levels, each game is played in a totally new maze, and may consist of any number of rounds that start identically for each player. Crabs can be played using your VIC-20 keyboard or joystick, and will work on all standard VIC-20 memory configurations.
