Kelly the kangaroo is enjoying a lovely picnic date with Rosie the rabbit in the picturesque Mossy Valley when - Oh no! The mad scientist Contemptus Mundy, always bitter and jealous of the happy people living on Gaia Gaia Island, has kidnapped Rosie and locked her away in his motherbase in the clouds! It's up to you to help Kelly save her sweetheart before it's too late and that vile Contemptus whisks her away to the stars.

Use the joystick to make Kelly hop to the left or right, and hold the fire button to perform a much higher jump to reach her goal. Contemptus Mundy's mothership has one weakness in it's anti affection forcefields and that is the prisoner's favorite food. In this case, strawberries! Kelly must collect six strawberries scattered around the obstacle course in order to free Rosie from her lame and apathetic captor.

Kelly will face many dangers along the way, from angry bees, carniverous flowers, agressive bats and automatic flying saucer drones. Most can be knocked out simply by jumping on them, but some are especially treacherous... watch out! If Kelly falls victim to these baddies, she will be knocked back several screens, losing precious time.
