Instructions: When the two wires in port 1 touch, the light box illuminates and the mechanism activates. Four creatures appear on the light box: a crab, an octopus, a seahorse, and a coral reef. Each creature has its own movement pattern (each time you press a button, the crab moves one square horizontally, the octopus moves one square vertically, the seahorse moves one square diagonally, and the coral reef remains motionless). Each creature moves within three squares, starting from the last square and starting over again from the first. Each press of the left, right, up, or down arrow keys moves the green block one square relative to the previous one. Successfully move the green block in the upper left corner from the GO position to the pearl in the lower right corner, and then successfully pick the pearl to complete the level. After completing the level, the two relays energize, and the power is turned on again to reset. If the green block touches the crab, octopus, or seahorse while moving, the game fails and you need to start over.
