Arc-a-Teks Earth is a building set for young children that allows them to create 2 characters: "Googie" and "Bluper". Each Arc-a-Teks set includes pieces to build two characters simultaneously and collector cards that reveal each Arc-a-Tek's name, residence, individual building style, and a secret arc-a-code. Young builders can use the codes to unlock additional characters at www.arcateks.com. Kids can also use the web site to learn more about the history of the Arc-a-Teks and their muse-like influence on many of Earth's own famous architects and inventors.
