First, the gang goes snowboarding with Chris Klug, then they hang-out with scientists at a NASA-like facility, next they jet off to a museum in Costa Rica, and finally end up at Mardi Gras in New Orleans. Along the way they encounter a snow monster, alien baby, "gigantisaurus," and the feuding Leland brothers, carrying their Civil War grudge beyond the grave. Cracking each case goes high-tech with a slew of internet-age gadgets in exciting new locales that land the gang in a variety of unlikely situations.
