Digits and the kids arrive in Shangri-La to save Master Pi, who has been imprisoned by Hacker.
With special guest star Geoffrey Holder. Out for revenge, Hacker invades Shangri-La and imprisons Master Pi. The kids and Digit arrive as Hacker searches for the Good Vibration - the source of peace and happiness on the cybersite. Trouble doubles with unexpected results for the kids as well as Hacker, Buzz and Delete. Will the good vibrations continue, or will Hacker turn Shangri La into Shangri Blah? The Big Idea: When something grows by doubling, it gets large surprisingly fast, growing ever faster the longer the doubling continues. Math Topic: Growth by Doubling; NCTM Links: Algebra *Science Connection: Comparing growth and patterns of change.
