Children break codes, build hideouts, send and receive messages and crawl through vents to complete math-based missions and become Spy Academy agents. Recruits don a disguise, practice their observation skills, help rescue agents trapped in the jungle, or find the correct sequence to unlock a series of locks. They follow a path of clues to discover a double agent and earn their Surveillance badge. Or they can test their skills in logic. Recruits crawl through a twenty foot long duct to watch the comings and goings of their fellow spies, listen in on conversations, or send messages. Recruits have to complete five missions to gain access to Agent Headquarters. When they do they become full agents, print out their new identity card and begin to earn badges to become a Master Agent and enter the Spy Hall of Fame.
