As our heroes prevent Dr. X from feeding the dinosaurs in the Lost World, Dr. X forcibly brings a monkey back to Technopolis. But the little monkey has stolen Twinkle's magic wand and accidentally casts a spell that makes him grow one hundred times his normal size. He starts playing with the city like his own private doll house. Our heroes will have to return the monkey to his normal size before Dr. X makes the situation worse by using all of his inventions to stop him.
