Hypno the Great bets Twipsy that he can make anyone computer-addicted, and he plans to try it on the first person mentioned in an e-mail. The victim happens to be Champ, the Walker family's decrepit old dog. Sure enough, Hypno wins his bet: Champ will do nothing but stare at the computer. Lissie asks Twipsy to help her turn Champ back into a normal dog again.
