It's a full-scale abduction. An entire day stolen by a mysterious alien UFO! Will Fester stand by and let it happen? The adventure kicks off now. First up, battle slime replicators, skeeters, globules, and massive scorpions. Your well-being is on the line—your very life! Will you conquer the Alien Bosses, or will they conquer you? Fortunately, you're not alone. This is a family mission. And what a unique family! Locate Thing, and help is just a step away. In a jam? Just call for Lurch. He'll hand those aliens a real L with a capital "L." The city's future rests in your hands, and the biggest challenge is waiting just around the corner!
