The Hacker pretends to be an exterminator who removes bugs and tricks the cybrarian, Ms. Fileshare, into letting him in the Cybrary. He did it with altered bar graph comparisons and made the scales on the two graphs different and he doesn't remove bugs, he adds them. Suddenly, he gets a case of amnesia and looses his memory. Now he has to work for Buzz instead of Buzz working for him. When the kids and Digit find bugs in parts of the Cybrary, they try to make a way to compare the number of bugs, so Ms. Fileshare will believe them.
